He said: "Terrorism is not the act of the bomb, terrorism's aim is to bring fear into people in the aftermath and the best antidote to fear is to build relationships and come together as a community.

The centre, at 53 Tib Street, is open from 10am to 6pm daily and anyone in need of support can also call the hotline on 0333 0124714.
