Israeli forces shot and killed a 17-year-old Palestinian boy in the occupied West Bank Friday, Palestinian health officials said, the latest bloodshed in a more than year-long cycle of violence that has gripped the region. The boy — whom Palestinian health officials identified as Muhammad Fouad Atta al-Bayed — was shot in the head by Israeli forces during unrest in the village of Umm Safa, north of Ramallah. The village has been a target of attacks by Jewish settlers in recent weeks.
