A 27-year-old Syrian asylum seeker blew himself up by detonating an explosive device which he carried along in a rucksack yesterday night, July 24, 2016 in the Middle-Franconia town of Ansbach, Bavaria. The man killed himself and injured 12 people after being denied entrance to a 2,500 people strong music festival held in the town with a population of 40,000 people as he couldn’t show a ticket.

The bombing took place at 10:15pm local time in front of the Eugens Weinstube wine bar, near the entrance to the Ansbach Open music festival. It was initially thought to have been caused by a gas leak. The suicide bomber was known to the police for trying to commit suicide twice prior to the bombing. He carried a backpack filled with screws, nails, and miscellaneous metal parts. Emergency personnel approached the bomber after the blast in an attempt to resuscitate, but the bomber was already dead.The video below shows the festival hours before the bombing.

The incident followed three other attacks in Germany within a week, including a machete attack that killed a pregnant woman in Reutlingen (Baden-Wurttemberg) earlier in the day, the OEZ shooting that killed nine people in Munich on Friday, July 22 and a train axe attack in Würzburg. Ansbach is located 150 kilometres north-west of Munich, near Nuremberg.

Investigators haven’t yet confirmed an Islamist link. Joachim Herrmann, the Bavarian interior minister, said that German authorities would investigate ways to prevent abuse of the asylum system.
