Syrian opposition activists say government warplanes have launched fresh air raids on rebel-held parts of the northern city of Aleppo.

Friday's airstrikes followed a brief lull in the morning, a day after scores people were killed in air raids and shelling in the contested city. Fears of more violence prompted religious leaders in rebel-held neighborhoods to suspend Friday prayers at the city mosques.

The Britain-based Syrian Observatory for Human Rights said one person was killed while another activist group, the Local Coordination Committees, said three died in the strikes. Several people were also reported wounded.

Syrian opposition activists say the northern city of Aleppo is mostly calm after days of intense shelling and airstrikes that killed dozens.

The carnage has propelled the city — contested since the summer of 2012 when opposition fighters stormed it and took over several neighborhoods — once again as a main battlefield in Syria's devastating civil war.

The Britain-based Syrian Observatory for Human Rights says there has been no major fighting or violence inside Aleppo since early Friday morning. The Observatory says a week of bombardments and air raids killed 123 people in rebel-held parts of the city and 71 and government-held areas.

An activist based in the city says the bombardment slowed down to a halt after midnight. He spoke on condition of anonymity, fearing for his safety.
