An Israeli official confirmed that it was the Mossad that provided a few years ago the information about Hezbollah's production plants located on the outskirts of London to British intelligence.

The Telegraph reported on Sunday that the Lebanon-based terror group stockpiled large quantities of explosive materials in London as part of a major terrorism plot,

According to the report, on September 30, 2015, British authorities, including MI5 and London police, acting on a tip from a foreign government, uncovered a major terrorist plot linked to Hezbollah in northwestern London.

Just months after the Iranian nuclear deal was signed, according to The Telegraph, British authorities uncovered three metric tons of ammonium nitrate hidden in caches found during raids on three businesses and one home in North West London. The raids were conducted after a months-long investigation headed by the MI5.

One suspect, a man in his 40s, was arrested in connection with the raids, the report said, though he was later released without charge. The plot had all the hallmarks of “proper organized terrorism” one official told The Telegraph, adding the bomb-making material could have done “a lot of damage”.

According to the Israeli official cited by Kan News, since the disclosure of the information, Hezbollah has transferred its manufacturing activity to other countries that have also been notified by the Israeli intelligence community.
