STOCKHOLM — A security guard at the Swedish prime minister's residence was killed Friday in what appeared to be a self-inflicted shooting, police and Swedish media said. The prime minister was not in the building. Police wouldn't immediately reveal how the man was killed, saying they wanted to inform his next of kin first. Tabloid Expressen said the victim died after shooting himself, but didn't cite any sources. Markus Friberg, a spokesman for Prime Minister Fredrik Reinfeldt, confirmed that the prime minister was not in the building when the shooting happened. Tabloid Aftonbladet said Reinfeldt was visiting the paper's office in Stockholm. — AP
