Israeli troops killed a 14-year-old Palestinian boy on Monday during a raid in the occupied West Bank that touched off confrontations with residents, medics and witnesses said. The West Bank, among areas where Palestinians seek statehood, has seen a surge in violence since Israel stepped up military sweeps in response to a spate of street attacks in its cities last year. Palestinian medics said the boy was shot dead in Dheisheh refugee camp, near Bethlehem, during what witnesses described as a face-off between Israeli soldiers and stone-throwers. It was not immediate clear if he had taken part. The army said troops opened fire after Palestinians attacked them with rocks, Molotov cocktails and improvised explosive devices. There was no word of any Israeli casualties.
