A man described by the FBI as an Islamic State sympathizer who hoped to mount attacks on U.S. soil was charged Tuesday with plotting to detonate a nail-filled backpack bomb on a Florida beach.

It’s the latest in a string of arrests targeting potential ISIS-related plots in the U.S. Earlier this month, the FBI touted its work in disrupting numerous such plans in places like the New York City area and Boston. …

The complaint says Suarez told an FBI informant he wanted to make a timer bomb, bury it on a Key West beach and detonate it remotely. Suarez was arrested Monday after taking possession of an inert explosive device provided by an FBI informant. Suarez had given the informant some bomb supplies, including two boxes of galvanized nails, the backpack and a cellphone to be used as a detonator, according to the complaint.

“I can go to the beach at the night time, put the thing in the sand, cover it up, so the next day I just call and the thing is gonna, is gonna make, a real hard noise from nowhere,” Suarez told an FBI source in a recorded call, according to the complaint.
