Oil prices extend gains on weaker U.S. dollar

The West Texas Intermediate for September delivery increased 1.43 dollars to settle at 48.22 dollars a barrel on the New York Mercantile Exchange, while Brent crude for October delivery gained 1.04 dollars to close at 50.89 dollars a barrel on the London ICE Futures Exchange. Enditem
