Rebels shell Syria's Aleppo, dozens killed and wounded

BEIRUT, Lebanon — State-run Syrian TV says rebels have fired a barrage of shells at government-held districts in the northern city of Aleppo, killing at least 20 people and wounding more than 100.

It says the shelling hit the area of Rahman Mosque and other districts in the contested city on Monday.

The Britain-based Syrian Observatory for Human Rights said more than 250 shells struck several neighborhoods of Aleppo, killing at least 13 people and wounding scores of others. The group said some people are still missing and the death toll is likely to rise.

Aleppo has seen heavy fighting and shelling since rebels seized part of the city in 2012.
