Around 20 youths rioted in a migrant camp near the German city of Bremen on Tuesday, in the latest incident of migrant violence to hit Germany.

Local news site NWZ Online says that two large grounds of groups started fighting at a shelter for unaccompanied minors, resulting in two teenagers requiring hospital treatment.

The reason for the dispute is not yet known, but police believe it could have been sparked by a mobile phone theft.

The centre, which holds around 100 young migrants who have travelled to Germany alone, is situated next to a primary school in the neighbourhood of Borgfelder Saatland. Nine emergency vehicles attended the incident, with police taking eleven Afghans into custody to determine their residency status.

The incident comes just one day after a brawl at another migrant centre for unaccompanied minors, which resulted in four people requiring hospital treatment.

The fight, in which a gang of Afghans and Iranians beat a group of Syrians with iron bars, broom handles, clothes hangers, happened at a centre in the city of Nuremburg. The cause of that incident also remains unknown.

Tensions have been growing as migrant centres across Germany fill up, with interethnic and religious violence becoming a serious problem.

Breitbart London has also reported on a fight between Christian and Muslim Iranians in Bad Fallingbostel, where both sides were described by police as “heavily intoxicated”. A total of 12 police officers were called in to calm the situation, with one migrant needing medical treatment.

Protests are continuing to grow in Germany as the influx of migrants shows no sign of abating.

Last weekend, the anti-mass migration Alternativ für Deutschland (AfD) party held a rally in Berlin which saw 5,000 people march through the streets of the German capital calling for the resignation of Chancellor Angela Merkel and the introduction of much tighter border controls.
