Air strikes have killed at least 27 people in rebel-held areas in Syria’s northwestern Idlib province, a monitoring group has said.
At least 21 people, five of them children, were killed in raids, including on a marketplace, in Idlib city, the UK-based Syrian Observatory for Human Rights said on Sunday.
“There were regime and allied Russian warplanes flying in the area today. But we do not know yet which planes had carried out the strikes,” the observatory’s head Rami Abdel Rahman told the DPA news agency.
Separately, aerial bombardments in the town of Maarat al-Numan, about 30km south of Idlib city, killed another six people, the observatory said.
Idlib city and the province by the same name is held by a coalition of rebel groups, including al-Nusra Front, a powerful Syrian group with ties to al-Qaeda.
Russia deployed warplanes to Syria last year to support President Bashar al-Assad against rebels seeking to end his rule. Moscow is also backing Syrian government forces in a separate fight against the Islamic State of Iraq and the Levant (ISIL, also known as ISIS) further east.
Several monitoring groups, as well as Turkish authorities accused Russia of conducting these air strikes, but Russian authorities denied any involvment.
The Syrian conflict, which began with peaceful protests in March 2011, has escalated into a multi-sided civil war.
The death toll has risen to more than 250,000 people while half the country’s population have been forced from their homes, according to UN estimates.
