Five men are accused of trying to blow up the Brecksville-Horthfield High Level Bridge just outside of Cleveland, Ohio are pleading not guilty.

The FBI had an undercover agent provide the suspects with explosives that wouldn't detonate.

Officials say the men not only planted the explosives, but pushed the detonator repeatedly.

Investigators say three of the men are self-proclaimed anarchists who formed a small group that considered a series of plots over several months.
