United Kingdom in May 2026: the most important developments in security
In the United Kingdom in May 2026, security news centred on attacks on Jewish communities and on tension with Iran and Russia. On 1 May a man was convicted of attempting a terror attack at the Israeli embassy in London. The UK raised its terror threat level to severe after a stabbing in Golders Green that targeted members of the Jewish community, and the United States told Americans in Britain to stay alert. A fire at a former synagogue in east London was the latest in a series of attacks; two people were arrested, and a second man was later charged with arson at a former synagogue in the same area. London police formed a new unit to protect Jews and added officers. Further cases followed: a man was charged with threatening to cut Jews' throats, another was charged after attacking two Jewish men outside a synagogue.
The Strait of Hormuz was the main foreign deployment. Britain sent the warship HMS Dragon to the Middle East around 9 May and said it would send drones, jets and a warship to join a defensive mission. On 11 May the UK and France convened 40-nation talks on a Hormuz security mission. UK maritime authorities reported attacks on ships and the seizure of a vessel off Fujairah. By 24 May the Royal Navy was preparing to clear mines while awaiting a possible peace deal in the Iran war.
Russia was the other focus. Russian warplanes repeatedly intercepted an RAF spy plane over the Black Sea, and an RAF aircraft carrying the UK defence chief had its GPS jammed near the Russian border. The head of GCHQ accused Russia of reckless assassination attempts and of targeting infrastructure, and said almost 500,000 Russian soldiers had been killed in Ukraine. The UK and Poland prepared to sign a defence treaty.
A London court heard that a Romanian man stabbed a journalist in London at Iran's behest, and a Greek man was charged with helping Iran spy on a Persian-language TV station.
