GAZA CITY (AFP) - Israeli troops killed a Palestinian gunman following a firefight in the north of the Hamas-run Gaza Strip on Monday, medics and the Islamic Jihad movement said. Medics said Khaled al-Kafarneh, 22, was killed when an artillery shell hit his house in Beit Hanun. The Islamic Jihad claimed in a statement that Kafarneh died in an Israeli airstrike following an exchange of fire between the armed group and Israeli troops near the border fence. "Following the firefight, helicopters intervened and fired two missiles," the movement said, adding that one of its members was killed and another listed as missing. An Israeli army spokesman told AFP that soldiers opened fire "at a fighter who was approaching the security fence" adding that "the device he was carrying exploded." Overnight Israeli aircraft carried out airstrikes on Gaza targets, causing damage but no injuries. Witnesses and Palestinian security sources said an Israeli F-16 fired two missiles against a police post near the southern city of Khan Yunis, sparking a fire. An Israeli helicopter also carried out a raid in an unpopulated area of Beit Lahiya in northern Gaza. "Aircraft intervened against a Hamas position in Hamas near Khan Yunis and another at Beit Lahiya," an Israeli army spokesman said. Palestinian fighters fired two rockets Sunday from the Hamas-run Gaza Strip into southern Israel that caused no injuries, the spokesman said.
