Palestinian drivers operating on dwindling supplies of fuel switched off their engines in the middle of a busy Gaza City road on Tuesday, blocking traffic to protest Israeli fuel cutbacks to the strip. Dozens of cars and trucks were plastered with banners in Arabic and English that said, "No to fuel restrictions." Drivers beeped their horns as the protest made its way slowly through crowded streets. Israel, which supplies nearly all of Gaza's fuel and half of its electricity, scaled back fuel supplies last month and has threatened to do the same with electrical power in an effort to deter Gaza terrorists from firing rockets into southern Israel. A spokesman for one of Gaza's fuel companies cautioned that gas stations would soon starting shutting down if the cutbacks weren't lifted.
