Russian and Syrian regime air strikes have killed 12 civilians in north-western Syria.
The Syrian Observatory for Human Rights said Russian air strikes on areas in the southern province of Idlib killed six civilians.
The monitor said the regime's raids also killed six civilians in the same area under the control of Al Qaeda-linked group Hayat Tahrir Al Sham, and wounded 27.
Earlier on Monday at least four people, including a woman and her child, were killed in air raids on Bsakla village, said the opposition's Syrian Civil Defence rescue group, also known as White Helmets.
Heavy shelling in the province, which borders Turkey, has killed more than 2,000 people, including hundreds of civilians, since the end of April.

On Wednesday, the Syrian military seized the town of Khan Sheikhoun from militants and allied rebels, and overran the countryside to the south, encircling a Turkish observation post in northern Hama.
On Saturday, pro-government fighters gathered north of Khan Sheikhoun to press on with the offensive.
