Israeli artillery shelling in the southern Gaza Strip Thursday afternoon killed three Hamas gunmen and wounded three more, Palestinian medics and witnesses said, according to DPA. An Israeli military spokesman in Tel Aviv, however said soldiers who came under fire from a rocket propelled grenade, opened fire with small arms, and reported hitting three gunmen. A fourth gunman was hit in an airstrike, the spokesman said. Palestinian witnesses said several Israeli tanks and two bulldozers had rolled into an area near a village by Khan Younis, and were attacked by Palestinian militant groups, who claimed to have fired more than 20 shells at the Israelis.
