A Palestinian man was shot dead on Monday by Israeli police troopers after he stabbed and lightly wounded one of them at a military checkpoint in the occupied West Bank, a police spokeswoman said. The incident came two days after a Palestinian was shot and killed and another was wounded during what Israeli authorities said were two knife attacks on troops in the West Bank. In both of those cases, Israeli personnel were lightly hurt. Violence has been simmering in the West Bank and East Jerusalem, among territories where Palestinians seek statehood.
