Police in Italy have arrested a man with explosive materials, thanks to an FBI tip.
The man came to the attention of the FBI after the 2017 truck attack in New York City, which left eight people dead.
The suspect had applauded the attack on social media. Police told Sky News24 that the man "could be dangerous," but didn't appear to have plans for an imminent attack.
The unnamed suspect is being held on the explosives charges while police investigate other possible charges.
