SINGAPORE:– Oil prices fell in Asia on Monday, giving up some of last week's sharp gains as concerns about a global supply glut weighed on prices ahead of fresh US stocks data.US benchmark West Texas Intermediate (WTI) for delivery in February was down 34 cents at $37.76 and Brent crude for February was trading 12 cents lower at $37.77 a barrel at around 0635 GMT. Prices jumped last week after data showed an unexpected fall in US commercial crude stockpiles, with WTI adding almost 10 percent.–AFP
