London, Four people were injured after a clash broke out between two groups at a gurdwara in Germany's Moers city, prompting a large-scale security response, including special forces, according to German authorities and media reports.
The incident occurred around 2:20 pm local time on Sunday during prayer time at the Sikh community centre when an altercation broke out between two groups present at the site.
Four people sustained minor injuries, including one who suffered a cut, police said in a press release. Arrests have been made.
Special forces were called in after witnesses reported hearing gunshots, and a police helicopter was deployed for a time.
Investigations by the criminal police and the public prosecutor's office are ongoing, the release added.
According to German public broadcaster Tagesschau, the confrontation is believed to have stemmed from internal disputes within members of the Sikh community.
