5Operations at the Shaybah plant were unaffected by the fire outside its perimeter walls.

The U.S. State Department ordered non-essential government employees and their family members to leave Saudi Arabia amid escalating attacks by Iran-backed Houthis on civilian targets, Reuters reported on October 21. Department spokesperson Tommy Pigott confirmed that the order covered those employees and their families "in Saudi Arabia only." The department said U.S. embassies in other Gulf countries would undergo temporary staffing changes, according to the Associated Press. The decision comes after Washington returned some diplomats to the region in recent months, having withdrawn some following Iranian attacks on U.S. facilities, according to Reuters. In Yemen, renewed fighting between the Houthis and Saudi-backed government forces led to the collapse of a truce that had lasted 4 years, according to the Associated Press. Iranian Foreign Minister Abbas Araghchi said in an interview on Tuesday carried by Reuters that Tehran had received no response from Saudi Arabia or the Houthis to its offer to help mediate peace talks.

In a development involving oil facilities, Saudi air defenses intercepted a drone that attempted to target a processing plant at Aramco's Shaybah field in the Eastern Province, Asharq Al-Awsat reported, citing an Energy Ministry source. The source said the fire resulting from the incident broke out "outside the plant's perimeter walls." Operations were unaffected, the source added. The Associated Press cited the Saudi Energy Ministry as saying debris from an intercepted drone killed 2 people and injured 2 others at an oil field operated by Aramco. The Energy Ministry did not attribute the attempted attack on Shaybah to a specific group, according to EFE.

In oil markets, Brent futures rose 0.78% to $109.64 a barrel at 00:22 GMT in early trading on October 21, according to Reuters. The rise came amid concerns over Middle Eastern supplies, before the diplomatic departure order was announced. Separately, the U.S. Energy Information Administration said commercial crude inventories, excluding the Strategic Petroleum Reserve, fell by about 3.1 million barrels during the week covered by its report. Inventories stood at 412.5 million barrels at the end of the week. That level was 3% below the 5-year average, according to the agency.

On air defense, Britain's Ministry of Defence said in its October 20 update that Typhoon fighter jets would conduct defensive missions to help protect Saudi airspace from drones and missiles. Britain had agreed, at the Saudi government's request, to provide a Voyager aerial refueling aircraft to support Saudi defensive activity, according to its statement issued on September 22, 2026. The U.S. State Department requires government employees working in Saudi Arabia to obtain special authorization to use any airport in the kingdom. The department advises U.S. citizens to prepare an emergency departure plan that does not rely on U.S. government assistance. In aviation, Lufthansa and Air France canceled flights to Riyadh until mid-November, according to the Associated Press. Cathay Pacific postponed the resumption of its Hong Kong–Dubai and Hong Kong–Riyadh routes until January 31, 2027, according to a Reuters report published on October 20.
