Israeli airstrikes kill four in Gaza

GAZA, May 10 (UPI) -- Israeli airstrikes on Hamas targets overnight Saturday in Gaza killed five "terrorists" and injured four "Islamic Jihad operatives," Israelis said.

The Jerusalem Post quoted Hamas officials and Israeli Defense Forces as saying the casualties were part of response to a Friday incident in which an Israeli man was killed by a mortar shell at a settlement in the western Negev region of Israel.

The Post also said Hamas' military wing, Izzadin Kassam, announced that a Saturday morning rocket barrage that damaged buildings but caused no casualties in the Israeli city of Sderot was, in turn, a response to the Israel's overnight attack.

The Israeli delegation to the United Nations this week presented a complaint to U.N. Secretary Ban Ki-Moon about frequent rocket fire aimed at Israel coming from Gaza, the Post said.
