Saudi Arabia’s largest oil processing facility at Ras Tanura has come under another drone attack, authorities have confirmed.

A spokesperson for the Defence Ministry said the unmanned aircraft attempted to strike the refinery complex but caused no damage. Initial assessments indicate the facility remains structurally intact, and there were no immediate reports of injuries.

The Ras Tanura site, operated by Saudi Aramco, is the company’s biggest domestic refinery and a key pillar of the kingdom’s energy exports. Earlier this week, a similar drone strike forced a temporary shutdown of operations at the same location, raising fresh concerns about the safety of critical oil infrastructure in the region.

Following the earlier incident, Aramco halted exports of liquefied petroleum gas, including propane and butane, though domestic supplies were not disrupted. The company said the suspension of some shipments could last for several weeks as it reassesses logistics and security arrangements.

The renewed attack comes amid heightened tensions in the Middle East. Since joint US and Israeli strikes on Iranian targets began, Iran has expanded its military response, targeting infrastructure and shipping routes across the Gulf region.

Oil installations in Oman and the United Arab Emirates have also been hit in recent days, while concerns continue to mount over the security of the Strait of Hormuz, a crucial passage for global energy supplies. About a fifth of the world’s oil and liquefied natural gas passes through the waterway.

The escalating hostilities have unsettled global markets. Brent crude prices rose above $82 per barrel, marking their highest level in over a year, as traders reacted to fears of prolonged supply disruptions.

With energy facilities increasingly in the crosshairs, governments and oil companies across the region are tightening security while exploring alternative export routes to limit potential fallout from further attacks.
