Oil prices surged more than 2 per cent on Wednesday, with Brent crude rising above $76 per barrel following renewed US-Iran hostilities.

The US launched strikes on Iran after Tehran was accused of attacking three commercial vessels in the Strait of Hormuz.

Washington reinstated oil sanctions on Iran, revoking a licence granted under a peace deal that had allowed Tehran 60 days of sanction-free oil sales.

Sirens were activated in Kuwait and Bahrain on Wednesday morning as regional tensions escalated following the US strikes.
