LONDON Aug 2 (Reuters) - Oil prices rose on Friday but were on course for a fourth successive weekly decline as signs of disappointing global fuel demand growth outweigh fears of supply disruptions on rising Mideast tensions.
Brent crude futures gained 46 cents, or 0.6%, to $79.98 a barrel by 0841 GMT, while U.S. West Texas Intermediate crude futures rose 51 cents, or 0.7%, to $76.82.
Both benchmarks have declined by more than 7% over the last four weeks in the longest streak of consecutive weekly losses this year.
