GAZA, May 6 (Xinhua) -- An armed wing of the Islamic Jihad (Holy War) claimed responsibility for launching three homemade rockets into southern Israel communities on Sunday.

    Al-Quds Brigades said in a statement that its militants fire done rocket into Sderot city from northern Gaza Strip and another group aimed two rockets at Israeli communities from southeast Gaza Strip.

    The Islamic Jihad said their attacks meant to respond to the Israeli army operation in the West Bank where three Islamic Jihad militants were killed two days ago.

    Israeli daily Yedioth Ahronoth reported that four rockets landed in open areas in southern Israel on Sunday morning, causing no injuries.

    Two rockets landed near southern Israeli town of Sderot and two others fell close to the border near the southern part of the Gaza Strip, the report said.

    Meanwhile, an Israeli army force stormed Jenin town in the West Bank and arrested a member of the Islamic Jihad after he was wounded during clashes with the soldiers.

    Militant groups in Gaza agreed to observe a truce with Israel that was reached last November but Israel's frequent raids against the West Bank and the consequent Palestinian rocket attacks from Gaza have made the ceasefire fragile.
