Shafaq News/ Oil prices rose on Thursday, supported by tensions in the Middle East, but failed to recoup most of the previous day's losses after a surprise build in crude stockpiles in the United States, the world's top oil consumer.

Brent crude oil futures rose by 29 cents, or 0.41%, to $70.66 a barrel by 0510 GMT, while U.S. West Texas Intermediate (WTI) crude futures increased by 33 cents, or 0.48%, to $68.48 a barrel. Both benchmarks fell by more than $2 a barrel on Wednesday.

"With tensions brewing amongst Iran and world powers over last week's drone attack, it seems nuclear deal talks will be lengthy and unlikely to provide imminent sanction relief for Iran," said Edward Moya, senior analyst at OANDA.

Israeli aircraft struck what the country's military said were rocket launch sites in south Lebanon early on Thursday in response to earlier projectile fire towards Israel. read more

The exchange came after an attack on a tanker off the coast of Oman last Thursday that Israel blamed on Iran. Two crew members, a Briton and a Romanian, were killed. Iran denied any involvement. read more

The U.S. State Department said on Wednesday it believed Iranians hijacked the Panama-flagged Asphalt Princess tanker in the Gulf of Oman but was not in a position to confirm.

Risks of potential supply disruptions amid a forecast for more storms in the Atlantic also supported prices, Moya said.

The National Oceanic and Atmospheric Administration (NOAA) on Wednesday revised upward its outlook for the 2021 Atlantic hurricane season, estimating there was a 65% chance of an above-normal season and between three and five major hurricanes. read more

Helping check gains, a rise in locally transmitted COVID-19 cases in second-largest oil consumer China has prompted restrictions in some cities and cancellation of flights and is threatening fuel demand, analysts said.

Prices also fell steeply in the previous session after the U.S. Energy Information Administration (EIA) said crude stockpiles rose by an unexpected 3.6 million barrels last week.

Some analysts, though, pointed to a bigger-than-forecast fall of 5.3 million barrels in fuel stockpiles.

"The fall in U.S. gasoline stockpiles to the lowest level since November 2020 suggests that fuel demand conditions in the U.S. are still quite resilient," analysts from Commonwealth Bank of Australia said in a note on Thursday.

The bank expects Brent oil prices to rise to $85 a barrel by the fourth quarter as oil demand outpaces supply growth.
