"Swedish police: Explosions were terrorism"

"STOCKHOLM – Swedish police said Sunday that two explosions in central Stockholm were an act of terrorism by what appeared to be a suicide bomber, who killed himself and injured two people on a busy shopping street.

Police would not comment on a motive for the Saturday attack. But a Swedish news agency said it received an e-mail threat just before the blast in which the writer claimed to have visited the Middle East "for jihad," and referred to the country's soldiers in Afghanistan and a cartoon of the Prophet Muhammad that outraged the Muslim world."
