Alleged Chemical Attack, December 8, 2012
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 December 8, 2012. It came in the form of an opposition video showing alleged victims of the incident near Aleppo, apparently Al-Safirah. It came as fears had been growing for a week over the Syrian government's alleged preparations for using Sarin nerve gas, and following statements suggesting that the United States would have to militarily intervene if the government engaged in any chemical attack. It also came two days after an unsupported claim of "toxic gas" being "thrown" in Daraya.
The active agent has not yet been guessed at by any public experts, but there are no indications in the video that Sarin was used in this case. Just what the video shows remains to be proven, as does whether or not it's deemed to have crossed Washington's "red line." Interestingly, opposition reports from the 8th and the days before and after make no mention of any chemical attack from any of their widespread sources.
The story was first broken (in English anyway) by Israeli media early on December 9, citing the just emerged video which was in turn posted on December 8. The Times of Israel was apparently the first, noting that their nation has been closely watching the issue, being "particularly concerned that Syrian chemical and biological weapons could fall into the hands of terrorists and be used against the Jewish state."  They reported:
- Syrian rebels on Saturday uploaded to YouTube a clip purportedly depicting victims of a chemical weapons attack perpetrated by the regime. The video shows Syrian civilians, some apparently dead and others injured, whose faces were disfigured in a manner that could be caused by a chemical agent. The rebels claim that the video was filmed in a suburb of Aleppo, where the Syrian regime reportedly maintains its largest depot of chemical weapons.
The report also added that the day before, a Free Syrian Army made a claim that it had captured, on the road to Damascus Airport, government trucks and equipment "meant to protect Syrian army soldiers from the effects of chemical weapons." 
Arutz Sheva, reporting just after, was quite clear in its interpretation:
- Fears of the worst possible scenario in Syria have been confirmed in a video released by rebels that shows victims of chemical warfare.
- An almost sure sign that Syrian President Bashar al-Assad has unleashed his chemical weapons for use against rebels is his regime’s claim on Saturday that rebels are preparing to use chemicals in their uprising. Assad systematically has accused opposition forces, which he labels as “foreign terrorists,” of carrying out attacks and murders for which his own loyalists are responsible.
- The Obama administration is bound to be tested this week on its treat [sic] to intervene militarily if signs continue to show that chemical weapons are already being used in Syria. If President Barack Obama thought that his warning would be enough to stop Assad, he apparently is mistaken. ... 
The video posting cited, 0:41 in length, is set in a clinic, and shows at least two wounded and two older boys apparently dead.  title Google-translated "The use of chemical weapons at the Ambassador City 12/08/2012." According to Google translate, the best reverse translation, visible in the title (السفير) is pronounced like Safir, a sound heard spoken at the video's start, where locales are usually given. Therefore, it could refer to the mid-sized city of Al-Safirah, about 12 km southeast of Aleppo, here on Google Maps.
The balance of people - a man, a woman, and two possible children - suggests perhaps a family that was stricken. They don't explain their own stories here. Much remains unknown about who they are and what happened.
The recent rhetoric suggested a particularly acute danger in the coming days, with Friday, December 7 standing out (the Muslim sabbath coinciding with America's day of infamy, that still signals serious war as it has since the Pearl Harbor attacks of 1941. The alleged attack in Al-Safirah only missed that deadline by a day, if that (the published on date is always a no-later-than point for any event). Such an incident as the first acknowledged chemical attack by the Syrian government, just announced as all but forcing U.S. intervention, should be well-reported by the accepted opposition sources, like the Syrian Observatory for Human Rights (SOHR) They don't seem to have full coverage for Friday and the weekend, Dec. 7, 8 and 9. They filed on the 7th about the death toll of the previous day, around 83. They used here a photo of several wrapped boys that was already used for the Daraya massacre. 
For Friday with at least 80 killed, they reported nothing consistent with this attack, although the town is apparently mentioned as suffering attacks: "In Aleppo 2 were killed. 1 was shot by sniper in the al-Iza'a neighbourhood of Aleppo city. 1 died of wounds he received days earlier by bombardment on the al-Sfeira town of Reef Aleppo," with reef meaning 'surrounding area of,' as with Reef Dimashq around Damascus. It further reported "in Aleppo province 4 rebels were killed. 2 rebel fighters were killed during clashes with regular forces in the al-Leirmon area of Aleppo city. 2 rebels from Reef Aleppo were found dead in the al-Seriyan neighbourhood of Aleppo city after detainment by one of the security checkpoints of the city."  December 8 and 9 do not yet have summaries posted.
The website of the Local Coordination Committees (LCC) is another and quicker source to check. The LCC is usually well-informed on what rebel forces are saying, but they apparently didn't hear anything about a chemical attack near Aleppo. Scanning their daily summaries for Friday and the weekend, Dec. 7, 8 and 9, Al-Safirah is not mentioned by name anywhere, so it must be lumped under Aleppo (where some of the given locations are relative to Al-Safirah will be worked out in time).
