Kurdish fighters from the Kurdistan Workers Party (PKK) congratulate each other after arriving in the Heror area, northeast of Dahuk, 260 miles (430 kilometers) northwest of Baghdad, Iraq, Tuesday, May 14, 2013. The first of Kurdish fighters from Turkey have entered northern Iraq as part of a peace deal to end a long uprising, despite Iraqi objections to the transfer. Comrades greeted 13 armed men and women from the Kurdistan Workers Party (PKK) at a ceremony in Heror in Iraq's self-ruled Kurdish area. The central government in Baghdad has rejected the deal, warning that the entry of more armed Kurdish fighters could harm the country's security. (AP Photo/ Ceerwan Aziz)
