French police have arrested three people in Nice in connection with the Bastille day attack.
A lorry ploughed into crowds watching a fireworks display on the seafront on Thursday night.
Authorities are trying to work out if the 31 year old driver – who was shot dead by police – had any accomplices.
An Irish man, originally from Galway, is said to be one of 52 people who are in a critical condition following the attack.
