Oil prices inched higher on Friday after three straight sessions of losses, as concerns over excess supply and weakening U.S. demand persisted. Despite the uptick, crude remained on track for a second consecutive weekly decline.
Brent crude futures gained 21 cents, or 0.33%, to $63.59 a barrel at 0149 GMT, while U.S. West Texas Intermediate (WTI) rose 22 cents, or 0.37%, to $59.65.
