Oil hits fresh 2016 highs as U.S. crude stocks fall

By Henning Gloystein SINGAPORE (Reuters) - Oil prices edged up to fresh 2016 highs on Thursday, buoyed by a fall in U.S. crude inventories, a weaker dollar and strong demand, although some analysts warned that the recent rally was starting to look overblown. International Brent crude oil futures hit a high of $52.86 a barrel, and were up 23 cents at $52.74 a barrel at 0700 GMT. U.S. crude hit a fresh high of $51.67 and was up 33 cents higher at $51.56 a barrel.
