A group of St. Pauli fans are said to have stormed a restaurant in Hamburg on Friday evening, injuring 22 people including two pregnant women.

Around 15 hooded supporters wearing red tube scarves reportedly targeted Paulaner's pub in Grossneumarkt which contained fans of local rivals Hamburger SV as well as 50 other guests not related to football.

Tear gas was sprayed and furniture and glasses were thrown as the two groups clashed, according to German newspaper Hamburger Morgenpost.

The incidents occurred ahead of today's derby match between the two teams in the German second division.

St Pauli put a dent in their rivals' title hopes by securing a 2-0 victory but there were further clashes between supporters and police.

The rivalry between the two clubs dates back to 1924 when St Pauli emerged as Hamburger's main competitors.

September 2018 marked the first game between the teams for seven years after Hamburger's relegation from the Bundesliga.

That meeting ended in a 0-0 draw with Hamburger winning the return fixture 4-0.

But today's victory gave St Pauli a historic double over their rivals.
