Thousands of police officers and firefighters from around the world are converging on Northern Ireland for their own version of the Olympic Games.
The World Police and Fire Games takes place over ten days and features a range of sports as well as some unique contests - including the "Stair Race" and the "Toughest Competitor Alive".
It is the first time the event has been held in the United Kingdom in the Games' 30 year history.
