An improvised explosive device (IED) detonated and damaged a restaurant near the Las Vegas Strip in the US state of Nevada, BBC reported.

The building, which houses Piero's Italian Cuisine and is across the street from the city's famed convention centre, was empty at the time of the explosion early on Thursday morning. 

A cleaning crew discovered the damage when they arrived about eight hours later and notified authorities of a suspected bombing, Las Vegas Metropolitan Police said, according to BBC.
