At least 23 Syrian civilians were killed Saturday in suspected Russian air strikes on a rebel-held town outside Damascus, a monitor said.
Elsewhere, the Islamic State group freed 37 Syrian Christians who were among more than 200 people kidnapped in February, an NGO said.
The strikes on the rebel district of Douma hit the centre of the town where markets are regularly held, the Syrian Observatory for Human Rights monitor said.
They appeared to have been carried out by Russian planes participating in an aerial campaign that began on September 30, the Britain-based group said.
