[LONDON] World oil prices fell on Thursday as some traders cashed in the previous day's gains won on the back of strengthening crude demand in the United States.
Crude futures also retreated on an apparent easing of tensions over the Ukraine-Russia crisis, traders said, although the crisis appeared to be reigniting on Thursday.
The US benchmark, West Texas Intermediate for delivery in June, slid 35 cents to US$100.42 a barrel.
Brent North Sea crude for June shed 56 cents to trade at US$107.57 a barrel approaching midday in London.
