Russian air strikes in a northern Syrian town are reported to have killed at least 18 people and wounded dozens more.
According to the Syrian Observatory for Human Rights, the air strikes targeted Ariha early on November 29.
The Local Coordination Committees, an activist collective, said missiles hit a busy market in the rebel-held town.
Ariha Today, a Facebook page covering events in the town, said the air strikes were carried out by Russian military jets.
There were conflicting casualty figures.
The Syrian Observatory for Human Rights said at least 18 people were killed and dozens more wounded.
Ariha Today put the death toll at 40 with 70 more wounded.
If Russian warplanes did carry out the November 29 air strikes it would be one of the deadliest incidents since Moscow began launching airstrikes in Syria two months ago.
Opposition activists say scores of people have been killed by Russian strikes since the air campaign began on September 30.
