Alleged Chemical Attack, August 10, 2016

August 10, 2016 (or, apparently August 11 in Syria): four civilians were reportedly killed by chlorine dropped "alongside" barrel bombs, on "the Zubdiya neighborhood of rebel-held Aleppo." Also, "The Syrian Observatory for Human Rights, a war monitor, said helicopters dropped explosive barrels on the neighborhoods of Seif al Dawla and Zubdiya, leading to the death of a woman and her child from suffocation."

Locations

 * Zubdiya area on Wikimapia as Zebdiyyeh - part of the Al-Ansari Mashhad district - north of Sukkari district, west of Bustan al-Qasr.
 * Seif al Dawla is just to its west (Wikimapia).

According to Peto Lucem's August 1 Aleppo situation map, Zubdiya is a front-line rebel-held district, while Seif al-Dawla was mostly a contested front-line district (middle of map). (August 20 map shows about the same, but clearer (top of map, in the middle)

Patients were taken to an "Al Quds hospital in Aleppo" with a manager named Hamza Khatib. If this is the same Al-Quds ACLOS has looked into, it's not in this district, but a ways south in Sukkari neighborhood, about one kilometer from the middle of Zubdiya (Wikimapia). This might be a more capable facility than anything nearby, but also is known for allegedly being reduced to rubble by a barrel bomb attack in April, and would host more chlorine attack victims in September. It might simply be best-known for its robust 'public relations department.'

Fatalities
Most reports say 4, but none gives details for more than 3. Most say a woman and her two sons. The VDC lists 3 killed - a woman and 2 boys from Zebdieh, all unidentified - woman's notes: She and her two children as a result of bombing an explosive barrel containing chlorine gas.

Al-Jazeera's report suggests who the 4th was: "One woman suffocated to death due to gas inhalation, along with her 10-year-old daughter and four-year-old son." So all told, it should be the woman, two sons, and a daughter. All of them seem to be unidentified by all sources. The two given ages (4 and 10) could be from withheld knowledge, or just visual guesses.
