At least 44 people were killed and dozens severely wounded in a suspected Russian air strike hit a busy marketplace in Idlib province, foreign news channel reported.
Russian fighter plane on Sunday carried out bombardment in Ariha town of the province which is reportedly under control of the Army of Conquest, a rebel alliance which includes the Nusra Front, the UK-based Syrian Observatory for Human Rights said.
According to a local news channel, Ariha al-Youm, cluster bombs were used in the aerial raid by a Russian fighter jet.
However, Russian defence ministry has not claimed the attack so far. It should be mentioned here that Idlib province is not considered as stronghold of terror group Islamic State (IS).
