NATION’S ‘WAY OF LIFE’ UNDER ATTACK: OFFICIAL

The Islamic State of Iraq and the Levant Tuesday released a video of the suicide bomber who struck the southern city of Ansbach issuing a pre-attack diatribe, prompting German authorities to heighten their investigation into the attacker’s links to the extremist group.

In Sunday’s attack, a rejected Syrian asylum-seeker — identified as 27-year-old Mohammed Daleel — triggered a backpack bomb, killing himself and wounding 15 people.

In the video, Daleel vows that Germans “will never sleep well again.” The figure, whose face is covered by a black scarf, vows to attack Ansbach in revenge over the “killing and displacing of Muslims.”

The attack was the fourth assault on German soil in less than a week and has rekindled concerns about Germany’s ability to cope with the one million migrants registered entering the country last year.

“The Islamic State is waging a brutal war of aggression ... against our way of life,” said Joachim Herrmann, the top security official in Bavaria, where three of the attacks took place. He said changes need to be made to European laws to allow for quicker deportation, while authorities in Germany need to investigate how the man was able to collect enough material to make at least two bombs in his room in an asylum-seeker home.
