U.S. crude futures turned lower on Friday and Brent fell more than $1 amid pressure from the dollar's strength after it recovered from earlier losses and as the U.S. front-month June contract headed toward expiration at the session's end.
A lower open on Wall Street for U.S. equities added to pressure on crude futures.
On the New York Mercantile Exchange, the expiring June crude contract fell 60 cents, or 0.61 percent, to $97.84 a barrel by 9:42 a.m. EDT (1342 GMT), trading from $97.70 to $99.60.
ICE Brent July crude fell $1 to $110.42 a barrel, having traded as low as $110.16 after slipping from an earlier peak of $112.30.
