What would be the first confirmed chemical weapons attack of the Syrian conflict (if confirmed, and it's not the first allegation) was reported on March 19, 2013, in Khan Al-Assal, a western suburb or outlying district of Aleppo (on Wikimapia). As usual, both sides in the conflict blamed each other for an attack that killed a reported 25 or 26 to perhaps 31 people with a toxic cloud, and wounded/effected 80-110 with acute respiratory and problems at the least.

As usual, both sides blamed each other, and this important alleged event remains incredibly confused and confusing, suggesting we don't know what's going on yet. This hasn't stopped strenuous posturing on the world stage about a firm response, probably against the Syrian government, whatever the truth of the matter. Considering the stakes, the truth of the matter is worth more study and though than it has yet been given.

There was also an alleged chemical attack the same day in Al-Otaybah, near Damascus (causing an unspecified number of "martyrs" and "a large number of wounded and many injuries"). While only the event near Aleppo is universally accepted and well-documented, both are worthy of proper scrutiny.

This page is a stub with a couple of sections up-front, and otherwise, as usual, being assembled on the discussion page.


A December, 2013 UN report (PDF) gives an attack time of 7:30 AM (Syrian government) and 7:00 (a witness). The report heard a single rocket was fired from Kfar De'il, five kilometers north, and landed at the upper yellow pin on the map they provided (below), 300 meters from an army checkpoint, releasing its toxic payload. An apparent breeze to the south-southwest caused fatal exposures at two homes red pins). The army checkpoint is not shown here, but one surviving witness apparently had his or her home indicated.

Introductory Video, Produced by Syrian Girl Partisan, the video below features ample footage from the hospital of the effected and the dead to strongly suggest mass exposure to a nerve agent. Numerous good points are also made that should spur some serious questions. Many of these are the same points we are or will be discussing at this page. [1]

Some evidence suggests chlorine was involved - witnesses described this smell, like bleach. A later UN report heard from witnesses the gas formed "a yellowish-green mist in the air," like chlorine, but had "a pungent and strong sulfur-like smell." They mention it caused itching, besides breathing and heart problems, foaming at the mouth, confusion, pupil consriction and vision problems, and loss of consciousness.

Later tests by Russian scientists showed sarin - an impure, improvised sort - was the main poison. [2] [3] The December, 2013 UN report was unable to confirm this, but didn't refute it or offer an alternate explanation. Sarin sems to be the consensus. However, there has been much specualtion on alternate poisons, some if which might remain relevant (see talk page, "The Alleged Agent(s)").

Chlorine and improvised sarin are now known to have been in terrorist hyands at this time. While they held no Scud missiles the world knows about, nor fighter jets (both reported as the delivery method), rebels did have plenty of home-made rockets, cited by the government as their munition (see talk page, "Propulsion: Rebel Rockets"). And it cannot be ruled out that some rebel group or other would be able to weaponize their chemicals to work with the projectiles they had. The Russian report, after analyzing the remnants, reported (as ambassador Churkin explained it):

"It was established that on March 19 the rebels launched an unguided Basha'ir-3 projectile towards Khan al-Assal controlled by the government forces," he said. "The results of the analysis clearly indicate that the ordnance used in Khan al-Assal was not industrially manufactured and was filled with sarin." [3]

The attack was against a disputed but government-held area (see below). According to the Syrian Observatory for Human Rights (and disputed by no one), 16 of the 26 dead were government soldiers (the other 10 were civilians). [4] According to Alex Thomson of UK Channel 4 News, other soldiers were on hand to help the wounded, and there is also a sectarian aspect; "Rebel Sunni groups with al-Qaeda sympathies have been attacking the town, where the population is predominantly Shia." [5]

U.N. Investigation Overview

The United Nations, following a request from Damascus and considering competing requests from rebel groups and allied governments, agreed to launch an investigation into the attack. See UN Investigation for a detailed account, or the external article Was the Syria Chemical Weapons Probe "Torpedoed" by the West? (May, 2013, with 2016 updates).

Brief summary: Syria's request was frustrated by Western (US, UK, France) demands that the same-day Damascus attack and an older Homs attack must also be investigated, and eventually that the investigators must be empowered like weapons inspectors were in Iraq. Agreements were allegedly reached and then broken through the spring. UN disarmament chief Angela Kane and chosen investigator Ake Sellstrom visited Damascus in late July, on the 26th announcing an agreement to investigate Khan al-Assal. This was already frustrated by a rebel re-conquest of Khan al-Assal on the 22nd, which was followed by a massacre there, perhaps including witnesses. Nonetheless, inspectors finally arrived on August 18. Two days later, they were still in Damascus when the massive Ghouta chemical attack occurred in the surrounding areas, and they switched to investigating this, finding sarin.

Later they came back and investigated the Khan al-Assal attack. As WhoGhouta analysis of their December, 2013 report explains:

The fact that a chemical attack occurred was already known, but the report adds two interesting findings:
Syrian soldiers were indeed attacked and the site was under Syrian government control at the time. These claims by the Syrian government were not widely accepted prior to the report.
The agent was an organophosporous compound. This matches the Russian’s finding of sarin in soil samples, but was also not widely accepted, especially since some eyewitnesses reported a Chlorine smell.

This also explains how the report failed to address delivery method (rocket/missile type), and how the attached map of affected area suggests about 20kg of sarin was used.

Russian Official Statements

  •, 9/10 July 2013
    Churkin, Russian representative at the UN, is quoted by RIA Novosti: According to the information at our disposal, the production of unguided projectiles "Bashair-3" was launched in February 2013 by the so-called "Bashair al-Nasr" brigade, connected with the Syrian free army." According to Churkin, soil samples taken at the site of the chemical attack, carried out on March 19, were delivered to Moscow. The studies were carried out in a laboratory certified by the Organization for the Prohibition of Chemical Weapons. It was found that sarin was produced not in industrial conditions, but in a handicraft lab.
  • RIA, TASS, 28 September, 2013
    Russia has enough professional evidence that the sarin gas, used on March 19 (2013) in the Aleppo area, was homemade, made in handicraft conditions, Russian Foreign Minister Sergei Lavrov said. The results of the investigation of Russian experts are available to all members of the UN Security Council. "We also have information that during the notorious episode of August 21 (2013), when chemical weapons were used, and this is an established fact, sarin was also used, and had about the same origin as the substance used on March 19, but only of greater concentration. We transferred this data to our American partners and to the UN Secretariat, "the minister said in an interview with the First Channel. Lavrov also recalled that the Syrian government had provided Russia with materials pointing to the involvement of the opposition in a number of incidents involving the use of chemical weapons. All these materials must be subject to a thorough examination, Lavrov stressed.

The days surrounding the the March 19 alleged chemical attack(s), trying to cross the "red line," feature an odd abundance of signals and invitations to get the line crossed. "Red line" of course refers to U.S. President Obama's announcement that any use of chemical weapons by the Syrian government will trigger U.S. military intervention. So might said weapons being in danger of falling into extremist rebel hands, or Hezbollah's hands, or perhaps just being moved around. But actual attacks as a tool of war were the main concern. A december 3 reminder in a speech by Obama was followed by the first (unconfirmed) allegations of such attacks on December 6, 8, 22, and 23, at least.

These first attacks failed to spur intervention, and for months, few if any such claims came across the wires. Then, on March 15, the rebellion had its two-year anniversary, with chances for everyone to mark the occasion. That day, the U.S. treasury issued a decree allowing US citizens to ignore sanctions and directly finance the Syrian rebels. [6] On on March 18, as Britain and France continued lobbying the E.U. to lift the arms embargo, Secretary of State John Kerry announced that "the United States does not stand in the way of other countries that have made a decision to provide arms" to the rebels. [7] Further, the top U.S. military commander in Europe - Adm. James Stavridis - said that NATO was laying out plans for possible military attacks on Syria, if an adequate reason should surface. [8]

On the 18th, one of the Syrian opposition groups abroad finally elected, with a few dozen votes cast, what they called a new Prime Minister of Syria: Ghassan Hitto, a naturalized U.S. citizen and member of the Syrian American Council. CNN reported that the council "said the decision should assuage the Obama administration's concerns about who would lead Syria should President Bashar al-Assad be deposed. "This question has now been answered," the council's statement said." [7]

Considering all this, it's clear that the morning of March 19 was an especially poor time for Damascus to cross the red line of its own accord, and a very opportune one for any rebel provocateurs to do it for them. That the attack that occurred then shows that someone seized the moment offered by this confluence of other people's decisions.

Interestingly, someone may have planned a three-attack day just then, hitting each of Syria's three largest urban areas. The Khan al-Assal attack at about 7:30 am coincided, apparently to within minutes, with the lesser-known alleged CW incident in Ateibah, Damascus suburbs and with a briefly reported gas release in the Baba Amr district of Homs sometime the same day.

Who Controlled Khan Al-Assal?

This can get a bit complicated. Most sources pass Khan Al-Assal as either government-held (a majority of sources) and thus, more likely to be hit by the other side, or call it a rebel neighborhood (rebel fighters and leaders), making it less likely or ludicrous to be a rebel attack.

Official sources specify the government restored order to "parts of" Khan Al-Assal in November, 2012. But in recent weeks, rebels have made gains back in, taking over the police academy and perhaps further, with the government re-establishing almost total control on March 17, two days before the chemical attack. Rebels must have still held the police academy; they say the missile strike was aimed at their position there but missed. But it happened to successfully come down right by a Syrian military target of some sort, if reports that numerous soldiers were killed are true.

  • SANA: The armed forces restored security and stability to parts of Khan al-Asal area last November. [9]
  • Alex Thomson: The area it hit, Khan al-Assal, has been in government hands since 17 March in an area where control often changes hands rapidly between the rebels and the Syrian Army [10]
  • SANA: ... (rebels) launched a missile at 7,30 in the morning from Kfar Dael region into Khan al-Asal area in Aleppo governorate. "The missile fell in a region populated by civilians on a 300- m distance from the post of the Syrian Arab army soldiers," the Ministry said in the letters. [11]
  • Voice of America: Other rebel leaders told VOA in telephone interviews that it would make no sense for them to launch a rocket strike on a city they largely controlled. [12]
  • Reuters: A rebel fighter in Khan al-Assal, ... Ahmed al-Ahmed, from the Ansar brigade in a rebel-controlled military base near Khan al-Assal (the police academy? "about 2 km from the blast") said: The missile, maybe a Scud, hit a regime area, praise God, and I'm sure that it was an accident. After, he said: A fighter jet circled a police school held by the rebels on the outskirts of Khan al-Assal and bombed the area [13]
  • NYT: Another rebel commander, Abdul Jabbar al Okaidi, head of the rebel military council in Aleppo, said in a telephone interview that he had witnessed the attack, describing it as an errant strike on a government-controlled neighborhood, by Syrian warplanes flying at high altitude. [14]
  • NYT: Anti-government activists suggested that the government might have concocted the chemical attack story to cover up an episode in which it accidentally fired a Scud missile on a government-held area. [14]
  • AFP: "We have neither long-range missiles nor chemical weapons. And if we did, we wouldn't use them against a rebel target," Louay Meqdad, a spokesperson for a rebel group, said. [15]

No Evidence for Rebel CW Capability?

One of the core issues in what's increasingly recognized as a distressing "whodunnit" is who could have done it. The rebels are not known to possess Scud missiles, as some rebels themselves describe the delivery system (nor do they have fighter jets, as some other rebels claim). But they do have all kinds of unguided rockets, one of which the Syrian government claims rebels used for their attack. Even at the long range the Syrians seem to have settled on - 45-50 km - the plausibility holds; rebels claim, inconveniently in the circumstances, to have a homemade model of rocket that can go 60 km.

(see talk page, rebel rockets for evolving details)

Nor are rebels known to possess deadly nerve agents, but the emerging consensus is those probably weren't used. Chlorine gas, which rebels are known to hold plenty of, appears to be an involved agent, perhaps the only one. However, it is not known for sure just what chemicals were used and how they were really delivered. And while there's no known precedent for a rebel-held, gas-emitting warhead, it remains at least possible.

World Reaction

With what happened on March 19 far from settled, how the world governments have reacted is of extreme interest. Stated tripwires of global war were allegedly triggered. The text that was here has been moved to the discussion page to let it develop and get sorted-out. Later, the summarized results will be inserted here.
