At Least 21 Killed in Syria

At least 21 people were killed in the town of Khan Sheikhoun when Syrian security forces opened fire Tuesday during a funeral procession. A rebel spokesman claimed that more than 50 people died in the attack, which took place during a visit of U.N. monitors to the town. None of the monitors were wounded, but the vehicles in which they were traveling were damaged. A United Nations spokesperson said the convoy was hit by an improvised explosive device, and the monitors were forced to use vehicles to flee.
