UK 2001: Bradford race riots

The Bradford Riot was a short but intense period of rioting which took place on July 7, 2001, in Bradford, West Yorkshire, England. It occurred as a result of heightened tension between ethnic minority communities and the city's white majority, stoked by confrontation between the Anti-Nazi League and far right groups such as the National Front.[1][2] Similar race riots had occurred a few days earlier in other parts of northern England.

Violence broke out in the city centre at 1630 BST after crowds at an Anti-Nazi League rally discovered that National Front sympathisers were gathering in a nearby pub.

When police reinforcements arrived, in full riot gear, anger turned towards them.
