Khalid Saleh, president of the Media Office, said that the UN Security Council has a duty to maintain international peace and security, and to neutralize Assad’s air force. The UNSC must make efforts to protect innocent civilians." Saleh also said that serious and immediate steps must be taken to stop the systematic violence against the Syrian people, which is beyond a doubt a war crime against humanity." Assad forces have recently unleashed a fierce military campaign against residential neighborhoods in Aleppo, carrying out brutal and indiscriminate barrel bomb attacks on the unarmed civilians. Activists in Aleppo said that more than 30 civilians were killed in the neighborhood of Sha'ar as a result of aerial shelling."
