Twelve people have been injured after an attacker detonated a nail bomb outside an open air music festival in the Bavarian town of Ansbach. The attacker was a 27 year old Syrian man who was denied asylum and faced deportation. He detonated the device after being denied entry to the festival for not having a ticket. Following the blast the public were evacuated from the area. Details are yet to emerge about the man’s motives and intentions, but this has been the latest in a string of attacks that have taken place in Germany and across western Europe.
