The Gaza Strip's ruling Hamas militant group is using its police cars to ferry around Palestinians because of severe fuel shortages in the area. The blue police cars are marked with orange stickers that read "we are ready to drive you for free." Transportation has been paralyzed throughout Gaza since Israel restricted gasoline and diesel supplies last month. Gazans now walk, ride bicycles or use vegetable oil in their cars to get around. Israel has steadily limited fuel supplies to Gaza to pressure Palestinian gunmen to halt their rocket barrages on neighboring Israeli communities. But it's widely believed that Hamas has hoarded its own fuel supplies. Some Gaza residents think the Hamas police taxis on Sunday were a publicity stunt.
