Airstrikes in north-western Syria on Thursday (June 7th), thought to have been carried out by regime ally Russia, killed 44 civilians including six children, AFP reported.
The raids, which hit a residential zone in the area of Zardana in the north-western province of Idlib, also wounded dozens more, the Syrian Observatory for Human Rights said.
The Russian defence ministry dismissed the Observatory's reports of strikes on Zardana as having "nothing to do with reality", in a statement carried by the TASS news agency.
The Observatory says it determines who carried out strikes according to flight patterns, as well as planes and ammunition involved.
The toll is likely to increase due to a number of victims still under the rubble, Observatory head Rami Abdel Rahman said.
Most of Idlib province lies beyond regime control and is held by an array of opposition fighters and extremists.
Zardana is largely controlled by Islamist opposition fighters, with a small presence of Tahrir al-Sham.
