Activists say Syrian military aircraft have targeted a rebel-held district in the northern city of Aleppo, killing at least 13 people.

The Britain-based Syrian Observatory for Human Rights says government war planes bombed the city’s rebel-held Shaar district on Tuesday morning. At least two children were among those who died in the attack.

The airstrikes are the latest in the government’s air campaign to drive out the opposition, which has controlled parts of Aleppo — Syria’s largest urban center — for more than a year.

According to the Observatory, Tuesday’s strikes were the third straight day the government’s air campaign against Aleppo.

On Sunday, 76 people, including 28 children, died in such strikes and the city was also hit by another round of airstrikes on Monday.
