Syria at war

Syrian rebels

said on June 21 they have received new weapons from friendly countries that

could lead to changes on the ground and victories against President Bashar Assad's forces. The civil war has killed tens of thousands of people, displaced more than four million and turned neighbor against neighbor, with civilians
