The toll in a deadly series of Syrian government air raids on a rebel-held town outside Damascus rose to 96 people early Monday morning, a monitoring group said.

The Syrian Observatory for Human Rights said regime warplanes on Sunday had conducted at least 10 air strikes on Douma, most of them hitting a popular marketplace.

"The toll documented by the Observatory has risen to 96 people, including at least two women and four children," AFP reports that the Britain-based monitoring group said early Monday.

It said another 240 people were wounded in the strikes, some of whom were in critical condition.

The Local Coordination Committees, a grassroots network of anti-regime activists, said overnight that at least 105 people had been killed in Douma, which lies in the opposition bastion of Eastern Ghouta.
