Serbian police arrested 17 people in the Muslim-populated area of Sandzak on Saturday after Friday's attack on the US embassy in Sarajevo. The 17 arrested were connected to Mevlid Jasarevic, who opened fire on the embassy, they say. Jasarevic was wounded and arrested following the attack. The detainees were followers of Wahhabism, a puritanical branch of Islam.
