A new report claims Israeli spies used one-ton remote-controlled weapons to assassinate Iran’s top nuclear scientist.

Israel’s Mossad intelligence service used a novel, next-generation weapon to assassinate the head of Iran’s nuclear weapons program, Mohsen Fakhrizadeh, according to a new report in the UK’s Jewish Chronicle.

The Mossad used a one-ton remote-controlled gun, which required an eight-month-long operation within Iran.
