A suitcase bomb has exploded near a migration office on the outskirts of Nuremberg, in Germany, today.

A loud blast rocked Zirndorf this afternoon and local reports suggested the device was a suitcase packed with aerosol cans.

Witnesses said they heard a loud bang about 200 metres away from the migration centre before finding a burning suitcase in an allotment nearby.

Police officers were seen standing in an alleyway next to a partially destroyed bag. No fatalities or injuries have been reported.

Police said they were looking for two people believed to have planted the device - a man in his 30s with a Mediterranean appearance and a woman believed to be aged about 25.

The explosion is the latest terrifying incident to hit Germany in recent days and comes barely 24 hours after a priest was brutally murdered by a pair of ISIS extremists in northern France.

Security services were seen evacuating the area minutes after the blast in Zirndorf at 2.15pm local time (1.15pm BST).

German police say they have deployed officers near a refugee accommodation center and a branch of the country's office for asylum seekers.

A statement from police said the public were never in danger but said officers were looking for two people in connection with the blast.

They are looking for a man in his 30s with a Mediterranean appearance. He had short black hair and was wearing a light blue shirt, jeans and white trainers.

Officers are also searching for a 25-year-old woman with black hair in a bun. She was seen wearing a black jumper with white red and red stars, as well as jeans and a jacket.

The explosion comes just three days after a Syrian asylum seeker blew himself up outside a music festival in Ansbach, which is also in Bavaria.

Mohammad Daleel, 27, was turned away from the festival before detonating his device, killing himself and injuring 15 others.

The 27-year-old had pledged allegiance to ISIS in a video filmed before the attack.

Two days earlier, an apparent lone gunman killed nine people in Munich.

The German-Iranian 18-year-old had no ties to ISIS but had an obsession with mass murderers such as Anders Breivik, who slaughtered 77 people in Norway in 2011.

On July 18, an axe and knife-wielding migrant went on a rampage on a train in Wurzburg, seriously injuring four members of a tourist family from Hong Kong and a German passer-by.
