Syrian government air strikes killed at least six civilians, including four children, in Aleppo province on Thursday, despite a fragile two-week-old truce, a monitor said.

In neighboring Idlib province, at least 22 extremists were killed in air strikes over the past 24 hours, the Syrian Observatory for Human Rights said.

Some were carried out by government aircraft, others by aircraft of the US-led coalition, the Britain-based monitoring group said.

The civilians were killed early on Thursday when a government air strike hit a house in the village of Babka in the west of Aleppo province.

It said the death toll could rise because a number of the wounded were in serious condition.

Most of the dead in the Idlib strikes were fighters of the former Al-Qaeda affiliate Fateh al-Sham.

Two of the group’s commanders were among 16 fighters killed in a coalition strike on their convoy on Wednesday, the Observatory said.

More than 310,000 people have been killed in Syria since the conflict began with anti-government protests in March 2011.
