During Saturday afternoon when people in Stockholm were busy buying christmas gifts and getting ready for the holidays, a man suddenly blew himself up with a pipe bomb in the middle of a crowded street. This lead to bystanders being shocked and probably developing hearing disabilities.
Ten minutes before the bombing, an email sent to media and the Swedish security police, addressed to “Sweden and the people of Sweden”, and referred to the Swedish soldiers in Afghanistan and the paintings by Lars Vilk portraying mohammed as a dog. The message said:
Now your children, daughters and sisters will die, like our brothers and sisters and children are dying.
Witnesses to the event claim the bomber was yelling something in Arabic just before the bomb went off. The bomber was found dead in the snow together with a red backpack containing six linked pipe bombs, but fortunately, only one of them actually exploded, only causing damage to himself and no innocent people got seriously hurt. The bomb unit was called to the place of the event, and large parts of the area were cornered off.
