The Daily Telegraph newspaper reported Monday that the crisis with Iran could trigger sleeper terrorist cells and trigger terrorist attacks on Britain.
The report quotes intelligence sources as saying that terrorist cells backed by Iran could cost attacks in Britain if the crisis between London and Tehran worsens following Iran's detention of a British flag carrier in the Gulf of Hormuz.
He adds that intelligence agencies believe that Iran has formed sleeper terrorist cells across Europe, including Britain, and may be ordered to launch attacks in response to the crisis in the Gulf.
These sources believe that the cells are run by militants linked to Hezbollah. Anti-terrorism police uncovered in 2015 a cell that collected tons of explosives in stores on the outskirts of London.
"Iran has put its agents in Hezbollah ready to launch attacks in the event of an armed conflict, and this is the threat posed by Iran to Britain's internal security," the newspaper said, citing intelligence sources, the Daily Telegraph reported.
She adds that the MI5 and the London police are certain that the 2015 raids have largely crippled Iran's terrorist activities in Britain, but that its sleeper cells are spread throughout Europe.
The Daily Telegraph reports that Iran is also accused of cyber attacks in Britain, including piracy targeting MPs in 2017, as well as an attack on the Postal Corporation, local administration networks and private sector companies by the end of 2018.
The group responsible for these attacks is believed to be linked to the Iranian Revolutionary Guards.
