The building suffered a direct hit earlier today and was extensively damaged according to Save the Children, a charity that supports the hospital.
The number of casualties is so far unknown.
Around 1,300 women and children are treated by the hospital each month, as it is the only maternity facility for about 70 miles, a spokesman for Save the Children said.
There were 340 babies delivered there last month.
The Syrian Observatory for Human Rights said that the air strikes also hit a civil defence building nearby.
Further strikes in another part of the province's countryside killed at least five people and seriously injured more than 25, they added.
