Explosions that killed an alleged suicide bomber and wounded two others in central Stockholm, Sweden, on Saturday have been dubbed “an act of terrorism” by Swedish police. The two explosions occurred within minutes of each other in a district full of Christmas shoppers, after Swedish police reportedly received threatening e-mails ten minutes before the bombs went off. It is believed that Iraqi Taimour Abdulwahab Al-Abdaly, a 29-year-old who lived in the U.K. with a wife and three kids, blew himself up after trying to set off a car bomb. On Sunday evening, London police executed a search warrant in Bedfordshire, north of London, in connection with the Stockholm blasts. If confirmed as a suicide bombing, the attack would be the first of its kind in Sweden.
