Gulf states, home to multiple US military bases, were on high alert on Sunday after US strikes on Iran raised the possibility of a widening conflict in the region. Saudi Arabia, the world's largest oil exporter, was on a high-security alert after the US strikes, two sources with knowledge of the matter told Reuters on Sunday, while Bahrain urged drivers to avoid main roads and Kuwait set up shelters in a ministries complex.

Tehran has previously warned that if it was attacked by the United States, it could target American assets in the region, including US military bases. Bahrain is home to the headquarters of the US Navy's 5th Fleet and there are US bases in Saudi Arabia and Kuwait, as well as in neighbouring Qatar and the United Arab Emirates. Nuclear authorities in Saudi Arabia and the UAE said they had not detected signs of nuclear contamination following the strikes in Iran.

"While the war has so far been contained in direct hostilities between Israel and Iran, direct US involvement is a critical threshold that risks dragging the Gulf states, notably Bahrain, Kuwait and Qatar, which host large US military facilities, into the conflict," said Hasan Al Hasan, a senior fellow for Middle East Policy at the International Institute for Strategic studies. He said the risk of an open conflict between the US and Iran could plunge the region into a devastating and potentially protracted conflict.

"In light of recent developments in the regional security situation, we urge citizens and residents to use main roads only when necessary to maintain public safety and to allow the relevant authorities to use the roads efficiently," Bahrain's interior ministry said in a post on X. Bahrain also told 70% of its government employees to work from home on Sunday until further notice, citing escalating tensions, according to the Civil Service Bureau.
