Shelling and bombings have become a part of daily life for civilians living in a war zone.
The Syrian regime and Russia have stepped up their air strikes on the country's largest city in the past few months, killing hundreds of people including scores of children.
Syria descended into civil war in 2011, after regime leader Bashar al Assad launched a crackdown on protesters who were demanding more freedom, democratic reforms and an end to corruption and repression. Since then, the ancient city of Aleppo has been a major battleground in the conflict.
The Syrian regime, backed by the Russian military, Iran's Revolutionary Guards and an array of Shia militias, have been attacking the city for months to drive out opposition groups.

Aleppo has symbolic value in the fight between the Syrian regime forces and the opposition fighters. It was the first province the Syrian regime lost in the opposition in early 2013 -- embodying Damascus' lack of control. It is the last big stronghold of the most effective opposition group - the Free Syrian Army, that is backed by the US, Turkey and Gulf Arab states.
