Riots in Nørrebro, Copenhagen, caused by the approval of the four Danish exceptions in the Maastricht Treaty referendum. Police open fire against civilians for the first time since World War II and injure 11 demonstrators.

Nørrebro is one of the 10 official districts of Copenhagen Municipality, Denmark. It is northwest of the city centre, beyond the location of the old Northern Gate (Nørreport), which, until dismantled in 1856, was near the current Nørreport station.
