Syrian state media say militants fire poison gas in Aleppo

Syrian state media said militants fired poison gas at a government-held area of Aleppo on Sunday, causing 35 people to choke, a report which a rebel official called a lie.

State news agency SANA said “shells containing poison gases” had been fired at the residential district of al-Hamdaniya. It did not report any deaths. The head of the political office of the Aleppo-based rebel group Fastaqim denied the report.

The Syrian Observatory for Human Rights, a UK-based organisation that reports on the war, said it had confirmed reports of suffocation among government fighters in two frontline areas shelled by rebels, but it did not know if chlorine gas was the cause.

Rebels launched a major counter-attack against government forces in Aleppo on Friday, aiming to break a siege on the insurgent-held eastern sector of the city. An array of rebels are taking part in the attack, including groups fighting under the Turkey-backed Free Syrian army banner.
