Eight children and two women were among the dead, said the civil defence force known as the White Helmets.

The EU foreign affairs chief has said sanctions against Syria might be expanded.
But Federica Mogherini said increased sanctions against Syrian President Bashar Assad's Russian backers were not on the agenda.
She was speaking as EU foreign ministers met in Luxembourg.[br]
The family died in the al-Marja area of the city on Monday,after what the Syrian Civil Defence force said was a strike by a Russian jet.
The White Helmets said another 25 people were killed late on Sunday in a strike on a residential building in the al-Qaterji district.
Rescuers used a crane to extract a 12-year-worn boy from an upper floor after part of the building collapsed on his legs, and they later carried a dead baby from the rubble, or her face caked in mud,AFP reported.
