Oil prices rose to their highest in two sessions on Monday amid concerns about oil supply disruptions from Saudi Arabia and elevated tensions in West Asia.
Brent crude futures increased to as much as $65.50 a barrel. The front-month contract was at $64.84, up 57 cents, or 0.9per cent at 0224 GMT.
US West Texas Intermediate (WTI) crude futures were at $58.61 a barrel, up 52 cents, or 0.9per cent, after earlier hitting a high of $59.39.
Despite efforts by the world’s top oil exporter Saudi Arabia to reassure global markets that it can resume full production by the end of this month after an attack on its largest oil processing facility in mid-September, buyers and traders remained sceptical.
