Minister of Security Sadik Ahmetovic and U.S. ambassador in Bosnia Patrick Moon talk after a news conference in Sarajevo

Serbian police arrested 15 people in raids on suspected radical Islamists on Saturday after a lone gunman opened fire with an assault rifle on the U.S. embassy in neighbouring Bosnia, Serbia's Interior Ministry said. Friday's broad daylight attack in the Bosnian capital paralysed central Sarajevo and had shopkeepers scrambling for cover as the gunman paced up and down firing on the embassy before a police sharpshooter wounded him and he was arrested.
