Thousands of protesting Palestinians marching from Ramallah to East Jerusalem clashed with Israeli forces on Thursday night, as violence spread to the previously peaceful capital. Demonstrators threw rocks, firebombs, and fireworks at Israeli security and border police, who in turn used riot-control methods and live ammunition. At least one was killed, while three others were left in critical condition, and 200 were injured. Twenty-seven Israeli officers were injured. Palestinians were marching against the two-week campaign in Gaza. Israel is deploying 3,000 to 4,000 police in Jerusalem, as riots are expected to break out there Friday.
