A Palestinian suicide bomber blew himself up at an Israeli army checkpoint in the southern Gaza Strip on Tuesday, killing a member of Israel’s domestic security force and wounding several others in defiance of a new call by the Palestinian government for guerrillas to cease attacks against Israelis. The Islamic Resistance Movement, or Hamas, asserted responsibility for the 7:10 p.m. attack at Gush Katif junction, at the northern entrance to the large Jewish settlement bloc of Gush Katif, along the Mediterranean coast. The group identified the bomber as Omar Tabash. No other information about him was immediately available.Full Story
