Apparent Russian air strikes killed at least 11 civilians on Sunday in two towns in Syria's north-western Idlib province, a monitoring group said. Nine people, including a child, were killed in strikes on areas in the town of Maaret al-Numan, the Syrian Observatory for Human Rights said.
Another two women were killed in Saraqib in the same province, the Britain-based monitor said.
It said both sets of raids were believed to have been carried out by Russian planes participating in an aerial campaign Moscow launched in Syria on September 30.
The Observatory relies on a network of sources on the ground and determines whether strikes were carried out by Syrian, Russian or US-led coalition aircraft based on the location of the raids and the types of planes involved.
Idlib province fell from government control earlier this year and is held largely by the Army of Conquest rebel alliance that includes al Qaeda affiliate Al-Nusra Front.
