Oil slips lower as dollar strength counters OPEC cuts

By Scott DiSavino NEW YORK (Reuters) - Oil fell more than 1 percent on Monday as a stronger dollar, ample U.S. supplies and excess speculative length outweighed OPEC output curbs and rising tensions between the United States and Iran. Brent futures were down 88 cents, or 1.5 percent, at $55.93 a barrel by noon EST (1700 GMT).
