Saudi Aramco has shut down its Ras Tanura refinery in Saudi Arabia following a drone strike in the area, according to sources familiar with the situation. The facility, one of the kingdom's largest refineries with a capacity of 550,000 barrels per day, was closed as a precaution while damage assessments are conducted.

A fire at the site has been brought under control, though the full extent of damage remains unclear. The Ras Tanura refinery sits on the Persian Gulf and plays a crucial role in Saudi Arabia's oil processing infrastructure. Aramco's media office declined to comment, and Saudi government representatives did not immediately respond to requests for information.

The attack comes amid escalating Middle East tensions, with crude oil prices surging 9.7% in London trading. The broader conflict has already disrupted maritime traffic through the Strait of Hormuz, a vital chokepoint for global oil shipments. Energy markets are particularly sensitive to attacks on major infrastructure, as even temporary disruptions can cause significant price volatility.
