Fuel shortages caused exasperation to spill over into anger on Friday amid a desperate race to get power restored and get stricken US cities moving again after the devastating superstorm Sandy.
Fights erupted in huge queues at the few gasoline stations still operating in the states of New York and New Jersey, with authorities in some towns and cities rationing fuel even for the police.
As the American death toll from Monday's mammoth storm hit 95, authorities said they were putting huge resources into helping the needy, restoring power and getting mass transit moving again.
