He also said four protesters were killed in clashes between security forces and protesters in the northern cities of Latakia and Idlib. Tens of thousands of people took to the streets nationwide Sunday as part of the monthlong uprising against the country's authoritarian regime. Syrian security forces in uniforms and plainclothes have launched a deadly crackdown on demonstrations, killing at least 200 people, according to human rights groups.
