Israeli troops killed two Palestinians during an arrest raid early Sunday, Palestinian officials said, raising the death toll to eight in a two-day surge of fighting. The Al Aqsa Martyrs' Brigades said the men were killed after Israeli troops surrounded a building and ordered people out. Most occupants came out, but the two Palestinian fighters remained holed up inside. An exchange of fire broke out, and the two men were killed, the group said. The group said the dead included Amin Lubadi, a bomb maker who had been wanted by the Israelis for more than three years. Palestinian medical officials confirmed the deaths of two men.
