" British terror suspects arrested in August were trying to construct a dirty bomb and planned to attack targets in London, including the Heathrow Express airport rail line, Time magazine reported.
Information from computer files seized with the group revealed plans for specific attacks in London including "blowing up high-rise buildings housing multinational companies" by driving bomb-laden cars into underground garages, Time said in a release on Sunday of material from its latest edition.
Other targets included the Heathrow Express, a rail line between the airport and London, and an unspecified synagogue. There were also plans for "hijacking a gasoline tanker and smashing it into a building."
They could do far worse with a tanker than crashing it into a building.
