A German security guard who turned an ISIS suicide bomber away from a music festival just minutes before he blew himself up said the jihadi ‘he kept staring at me nervously’.

Pascal Bohm, 25, saved scores of lives when he denied Syrian Mohammad Daleel entry to the 2,500 sell-out concert in Ansbach because he didn’t have a ticket.

Mr Bohm, 25, said Daleel seemed nervous and frantic as he loitered outside the venue after he had been rejected.

'He seemed to hope that I would leave my place. He kept phoning someone and had his hand on the ear,' the hero told German newspaper Bild.

'I noticed him because he kept staring at me nervously.'

Concert: Bohm, 25, stopped Daleel from getting into the 2,500 strong festival in Ansbach because he didn't have a ticket. He said the ISIS killer kept staring at him nervously. Just 30 minutes later he detonated his bomb

'Every movement seemed frantic, and he looked to see if he was being watched,'

Bohm's chilling encounter with Daleel, a failed asylum seeker who was twice meant to be sent back to Bulgaria, came just 30 minutes before he detonated his rucksack packed with screws and metal shavings outside Eugen's Wine Bar in the city 50 miles west of Nuremburg in southern Germany.

The blast injured 15 people - four seriously, and killed the Daleel, 27, who had links to ISIS.

Describing the moment the explosion went off Bohm said he felt a 'shock wave' and saw chairs flying through the air.

He said: 'I only saw injured people lying in blood on the floor - I immediately called the ambulance and fire brigade.

'The backpack wasn't on the man, and his body was not torn. He also had no visible external injuries, there was only a little blood', he said.

The attack could have killed many of the 2,500 concert goers if the bomber managed to get inside.

Barvaria: The explosion took place in the city of Ansbach, 50 miles west of Nurenburg, in southern Germany

ISIS released a video showing Daleel issuing a chilling warning that Islamists will wreak havoc across Europe with car bombs.

The failed asylum seeker warned the West they will no longer 'live peacefully' and that they will be much larger bombings than the one he carried out in the quiet Bavarian town on Sunday.

In the video Daleel said: 'This operation is carried out with an explosive device, but next time it will be with (car) bombs. To the German people, your country is killing you by its actions. Islamic State did not start this war with you.'

Daleel, whose face is totally obscured by a black scarf, attempted to justify what German politicians have called a 'cowardly act'.

Video: ISIS have also released a video this evening which appears to show Daleel pledging his allegiance to the terror group

The bomber added: 'To the German Youth: your planes that are shelling us don't distinguish between men, women and even children.'

The twisted video emerged after ISIS issued a photograph of Daleel, who was nicknamed Rambo, to glorify his suicide bombing.
