Brent crude oil futures slipped from near 105 dollars a barrel on Friday, with ample U.S. inventories and a poor demand outlook weighing on prices, after bouncing more than 3 percent in the last two sessions off this week's low. So Brent crude slipped 23 cents, to 104.71 dollars a barrel. U.S. oil gained 6 cents, to 96.75 dollars a barrel. The European benchmark had rebounded from 101.82 dollars a barrel hit on Tuesday because of a weak dollar, even though top industry bodies such as the International Energy Agency forecast a bleak demand growth outlook. The dollar remained in the doldrums on Friday, after hitting a fresh four-month low against a basket of currencies in early trade.
