Quds city, October 29, SPA -- Israel restricted the flow of fuel to Hamas-controlled Gaza on Sunday, a move it vowed to take in response to "the incessant firing of rockets into Israel," an adviser to Prime Minister Ehud Olmert said. Ten Israeli and Palestinian human rights groups are petitioning Israel's Supreme Court to stop the reduction. The Israeli company Dor Alon supplies fuel to Gaza. Dor Alon had previously halted fuel shipments following Hamas' takeover of Gaza earlier this year, but restarted them. It's unclear how the new reductions will affect Gaza's power plant, which is fueled by Dor Alon. The Israeli daily, Haaretz, reported the power plant received a full supply of fuel Sunday. But Ahmed Ali, deputy director of Gaza's Petroleum Authority, told The Associated Press that fuel shipments on Sunday were more than 30 percent below normal. He said Israel delivered 52,835 gallons of diesel fuel, compared to the typical 92,500 gallons on a normal day, and 23,775 gallons of gasoline, instead of the regular supply of 40,000 gallons. He said Gaza keeps about four days of fuel reserves, the AP reported.
