The death toll is likely to rise due to the number of seriously wounded.Strikes on the area intensified following an attempted jihadist attack on a coalition base in the nearby village of Al-Bahra.
Meanwhile , a UN aid convoy has reached a camp for displaced Syrians near the Jordanian border.
The convoy was meant to arrive at Rukban camp on 27 October, but was postponed for security reasons.
More than 70 trucks would ferry in more than 10,000 food parcels and bags of flour, as well as clothes for 18,000 children.
The aid would also include newborn baby kits for 1,200 children, medicines, medical supplies and nutritional supplements for children and women.
It was the first aid convoy to arrive in Rukban from Damascus, after the last delivery from Jordan in January.
