BEIRUT (Reuters) - Fierce fighting and air strikes broke the third day of a unilateral Russian ceasefire in the northern Syrian city of Aleppo on Saturday, the Syrian Observatory for Human Rights said.
The first Syrian or Russian air strikes on Aleppo, Syria's most populous city before the war, since Russia began the pause in hostilities on Thursday hit a key front line in the city's southwest.
Ground clashes and shelling, which had continued throughout the day on front lines between government-held and insurgent-held parts of the divided city, intensified.
