    GAZA, Nov. 27 (Xinhua) -- Palestinian fighters fired two rockets into Israel late Wednesday and Israel decided to keep Gaza Strip crossings closed in response, local sources said on Thursday.

    No Palestinian group claimed responsibility for the rocket attack which came hours after Israel told the Palestinian side that Kerem Shalom cargo crossing, which was open on Wednesday for a convoy of aid, would remain open for Thursday.

    45 trucks of aid, including 20 for the United Nations Relief and Works Agency (UNRWA) and 25 trucks of frozen food and dairy products for private companies were supposed to get into Gaza Thursday, according to Palestinian officials.

    Israel first sealed off Gaza Strip last year after Islamic Hamas movement seized the territory. But in June, Egypt brokered a ceasefire between Hamas and Israel until sudden clashes between Hamas militants and Israeli soldiers in southeast Gaza rocked the agreement and inflamed a new wave of violence on Nov. 4.

    Since then Israel closed the crossing points and withheld fuel supplies to Gaza power plant except for three times.
