GAZA, June 11 (Xinhua) -- Two Hamas militants were killed in Israeli airstrike in the northern Gaza Strip on Sunday, witnesses and security sources reported.

    Meanwhile, a member of Islamic Jihad (Holy War) militant group was killed in an explosion in his house in the northern Gaza town of Beit Lahia.

    Medics said that Ammar Shihab was killed and another person was injured in the explosion.

    Palestinian sources said that a group of militants from Hamas armed wing Izeldein al-Qassam Brigades were hit by an Israeli air-to-surface missile when they were preparing to launch a homemade rocket on southern Israel.

    Palestinian medics said that two Palestinians were killed and one was critically wounded in the airstrike.

    Hamas militants broke a 16-month ceasefire and resumed rocket attacks against Israel on Saturday to avenge the killing of seven Palestinian civilians by Israeli gunboat shelling on the beach in the northern Gaza Strip Friday.

    The group claimed responsibility for firing more than 15 homemade rockets at southern Israeli towns over the weekend. Enditem
