US Secretary of State Mike Pompeo accused Iran of responsibility for the incidents and said the United States would raise the attacks at a UN Security Council meeting scheduled for later Thursday. Iran labelled the attacks "suspicious."
US oil benchmark West Texas Intermediate for July delivery finished up 2.2 per cent at USD 52.28. The advance marked a reversal from a sharp fall on Wednesday following a bearish US oil inventory report.
"Tension across the Middle East is high - and the attacks on two tankers has further exacerbated the situation, even though there does not appear to have been any damage to the cargos," said John Hall, chairman of British-based consultancy Alfa Energy.
A note from Eurasia Group said the "incidents appear aimed at demonstrating the vulnerability of Gulf shipping while damaging confidence in the US ability to protect freedom of navigation." Gains in oil prices have been "constrained by high inventories and concerns about the global economy," it added.
