A suspected suitcase bomb has exploded near a migration office in the town Zirndorf, near Nuremberg, in Germany.
The explosion was caused by a suitcase bomb, apparently full of aerosols.
It has not been confirmed yet if there were any casualties.
German media said the explosion occurred near the Federal Office for Migration in Zirndorf, Bavaria, where newly arrived refugees are processed.
According to media reports, a suitcase packed with highly inflammable aerosol canisters was detonated about 200 yards away from the building.
The city of Zirndorf has previously seen neo-Nazi marches in the past.
According to a police spokeswoman, armed officers have been rushed to the scene and a police operation is ongoing.
She added that witnesses heard a loud bang and discovered a burning suitcase on a footpath near the immigration centre.
Suitcase Bomb Explodes In German City
German media reported that police carried out a raid just yards from the reception centre on Wednesday.
Witnesses reported how people fled the scene in panic as a huge bang ripped through the quiet neighbourhood.
The German interior ministry this afternoon described the explosion as “small” and said that nobody had been injured.
Bavaria, in southern Germany, has been the entry route for more than a million migrants and refugees who have flooded into the country over the last 18 months.
Many have been settled in small towns across the region, with most being housed in reception centres at first before being found more permanent accommodation.
Germany has been on the edge, following a spate of Islamist-inspired terror attacks over the last week.
Recent attacks including an axe attack on a train and a suicide bombing at a music festival.
Last Friday a German-Iranian gunman went on the rampage in the Bavaria’s biggest city, Munich.
The gunman shot at crowds at a shopping centre before turning the gun on himself.
This is coming just days after a failed Syrian asylum seeker blew himself up in a suicide bombing outside a music festival in the Bavarian town of Ansbach.
