(Xinhua) -- The military wing of Palestinian President Mahmoud Abbas' Fatah movement claimed responsibility on Sunday for launching six home-made rockets into southern Israel. In a press statement, al-Aqsa Martyrs Brigades said the rocket attack was part of a campaign launched in late October, which includes rocket-fire into Israel "as long as the Israeli crimes continue." The rockets were fired on the city of Sderot in southern Israel and Western Negev. Israel sources said the power was briefly cut in Sderot because of the Palestinian rocket attack. Earlier in the day, an Israeli airstrike killed a militant from the Islamic Jihad (Holy war) movement while he was firing rockets in northern Gaza Strip. Jihad militant's death came after three Palestinian civilians were also killed this morning in northern Gaza.
