Syrian government forces and their allies bombarded insurgents in southwestern Aleppo on Tuesday, close to where rebels recently opened a corridor into the city's opposition-held eastern sector, pro-Damascus media reported.
Hezbollah's Al Manar TV said government forces had advanced to cut off rebel progress into opposition-held areas of Aleppo. A rebel official denied any government advance in the area.
Fighting in Syria's five-year civil war has in recent months focused on Aleppo, Syria's largest city before the conflict. Nearly 2 million people still live there.
