Swedish Police Probe Stockholm Blasts as Terrorism VOA News 12 December 2010 In this image from video, showing emergency services as they attend the scene after a car exploded in the center of Stockholm, 11 Dec 2010 Photo: AP In this image from video, showing emergency services as they attend the scene after a car exploded in the center of Stockholm, 11 Dec 2010 Police in Sweden say two explosions in central Stockholm that killed one person and injured two others was a terrorist attack. Police spokesman Anders Thornberg told a news conference Sunday the explosions are being investigated under Swedish law as an act of terror, but that authorities have not raised the security level. Police say the first blast Saturday occurred in a car near a busy shopping street, slightly injuring two people. Shortly afterward, a second explosion was heard on the same street. Police later found one person dead at the scene. Authorities believe that person was a suicide bomber. Swedish news agency TT said Saturday that 10 minutes before the blasts, it had received an e-mail in Arabic and Swedish, warning of unspecified "action." The news agency said the warning, also sent to the Security Police, referred to Sweden's involvement in Afghanistan and to caricatures of the Prophet Muhammad by the Swedish artist Lars Vilks.
