Crude oil prices plunged Thursday, with the WTI futures contract sliding below $100 a barrel in New York, after disappointing US economic indicators and a stronger dollar.
New York's main contract, light sweet crude for June, plummeted $9.17 to $100.07 around 1815 GMT, minutes before the end of trading on the New York Mercantile Exchange.
Earlier it had fallen as low as $99.70 a barrel, below the $100 threshold for the first time since mid-March, when Arab unrest and the Japan earthquake and tsunami disaster sent prices spiking.
