EU mayors tackled issues including migration, radicalisation and means of preventing terrorist attacks as they gathered in Brussels on Thursday for the conference entitled "Building Urban Defences against Terrorism: Lessons Learned From Recent Attacks."

"We all have our role to play in the fight against terrorism and in the fight against radicalisation at the level of Brussels and at the national level," European Commission member in charge of the Security Union Julian King said in a statement to journalists.

He added: "That's what we do here today to underline how we can work together both to better protect our public spaces, making it hard to carry out some of the horrible attacks we've seen."
