Female voters display their purple finger tips after casting ballots at an elementary school in Nasiriyah March 7. By law, women must fill 25percent -- 82 out of the 325 -- parliamentary seats. The heavy purple dye reduces attempts of double-voting fraud. No election day violence occurred in Nasiriyah, Iraq's fourth largest city bisected by the Euphrates River in the southern province of Dhi Qar. Iraqi security forces were responsible for all security.
