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.

A PKK official, Furat Jakrkhouni, said a larger group is expected to enter Iraq in a week if no problems emerge.

In March, the PKK and Turkey announced an agreement to end a nearly three-decade conflict that has killed tens of thousands of people. The deal includes refuge for PKK fighters in Iraq's Kurdish region.
