On Sunday, the General Command of the Army and Armed Forces released a statement announcing that the city’s al-Nairab district and its surroundings areas were targeted by militant mortar shells containing chlorine.

 The statement noted that the attack was carried out in response recent gains made by the Syrian army in south and west Aleppo in which large numbers of terrorist were killed and the militant’s inability to break to siege on city’s eastern neighborhoods.

It noted that such cowardly actions will only serve to increase the Syrian army’s determination to purge the Takfiri terrorists from the country.

Aleppo has been divided since 2012 between government forces in the west and the militants in the east.

Backed by Russian air cover, the Syrian army launched operations to purge the militants from the city in September.

This is not the first time the militants have launched chemical attacks on the city.

On November 3, they hit Minyan in west Aleppo with a toxic attack, injuring eight people and on October 31 they hit the city’s suburbs injuring 48 more.

The Organization for the Prohibition of Chemical Weapons (OPCW) is currently investigating the use of chemical agents in Syria by the request of the government in Damascus.

Last week, UN Secretary General Ban Ki-moon said Syrian militants’ use of chemical weapons may weaken the “taboo” against the use of such banned agents. 

 "It is imperative that those responsible for the use of chemical weapons should be held accountable," he stressed.

Earlier in the day, Syrian forces reclaimed several strategic areas on the western edge of the city, purging it from the presence of Takfiri militants.
