A bomb exploded Sunday in a Shi'ite mosque in this southern city, wounding at least two people, police said. The small bomb was placed in the room where worshippers wash themselves before performing the prayers, police reported. At least two people who were there preparing for prayers were wounded, he said. The Emir Mosque in the central neighborhood of Ashar is usually visited by Shi'ites from around Iraq because they believe that one of their 12 Imams, or saints, prayed in it in the ninth century. The explosion comes amid attacks on Shi'ites and Sunnis mosques following a Wednesday explosion that heavily damaged a Shi'ite shrine in the central city of Samarra.
