Britain's Foreign Office warned on Tuesday that "the risk of sudden escalation is high" in the Middle East, as three of the Royal Navy's four Vanguard-class nuclear deterrent submarines were reported to be at sea at the same time, the Liverpool Echo reported.
Updated Foreign, Commonwealth and Development Office guidance published on 27 October urged British nationals to prepare for possible flight cancellations and travel disruption across the region, covering airspace over Israel, Iran, Saudi Arabia, the United Arab Emirates, Qatar, Iraq, Jordan and Yemen.
The reason for deploying three submarines at once was not made clear. At least one is believed to be carrying nuclear warheads on routine patrol, according to Sky News. One vessel is thought to be preparing to take over patrol duties, and a third may be undergoing sea trials, according to an unnamed expert. The Times, which first reported the deployment, cited a source who called having three submarines at sea simultaneously "unusual." The fourth submarine, HMS Victorious, remains under maintenance at Devonport naval base.
A Ministry of Defence spokesperson said Britain's nuclear deterrent was "the cornerstone of our national security" and that the UK was "the only European ally to commit its nuclear deterrent to the defence of NATO," meaning all NATO members benefit from its protection.
The Foreign Office warning cited Iran's public statements that it intends to strike sites linked to the United States and Israel as regional tensions mount. Oil prices eased on Tuesday on hopes of diplomatic progress, even as Yemen's Houthi rebels said they had struck Saudi Arabia's Ras Tanura refinery, the kingdom's largest, with a , according to Reuters.
Iran's security council chief, Mohsen Rezaei, met Tehran's supreme leader on Tuesday, a day after talks with representatives from Saudi Arabia, Turkey and Pakistan on reducing tensions, though officials gave no sign of an imminent breakthrough, Reuters reported.

Why it matters for Europe
Britain's four Vanguard-class submarines carry the UK's entire nuclear deterrent, which the Ministry of Defence says also protects NATO allies in Europe; having three at sea together is unusual given the limited availability the submarine fleet has faced in recent years. The warning comes as attacks on Gulf shipping and energy infrastructure, including the Ras Tanura strike, have kept tension high despite the renewed diplomatic contacts, with analysts cited by Reuters warning that a change of government after Tuesday's Israeli election could affect how the stand-off with Iran develops.
