The US State Department has issued a security alert for the Longitude festival urging US citizens here to avoid it.
However, gardaí have insisted the event is being 'policed appropriately'.
This weekend's festival got underway at Dublin's Marlay Park this afternoon, and will continue until Sunday.
However, the US Embassy in Dublin has issued a security alert.
On their website, the Embassy claimed: "Reports indicate a potential for violence at the Longitude Festival taking place from July 5-7, 2019, in Marlay Park, Dublin.
"Local police are aware of the threat and will conduct comprehensive bag and person searches. The police have increased event security and are monitoring the situation."
The warning was echoed in a tweet from the US State Department.
