Crude oil fell as supply concerns eased in Iraq and Libya. Futures dropped for a 10th day, poised for the longest retreat since the contracts began trading in 1983. Libya's production rose as output from the western Sharara field climbed, National Oil Corp. said. The fighting in Iraq hasn't spread to the south, home to more than three-quarters of its crude output.

WTI for August delivery dropped to $102.18 a barrel (-0.09%) on the New York Mercantile Exchange.

Brent for August settlement fell to $107.98 a barrel (-0.30%) on the London-based ICE Futures Europe exchange.
