The committee will "track the threat represented by the Kurdish Workers' Party to the security and the stability of Turkey and Iraq," Iraqi government spokesman Ali al-Dabbagh said in a statement.

It will also "enact forceful measures to stop all activities undertaken by this organisation inside Iraqi territory or in any region adjacent to the Turkish-Iraqi border," Dabbagh added.

The announcement followed a meeting to discuss the plan between US Ambassador Ryan Crocker, visiting Turkish Interior Minister Besir Atalay and Iraqi Prime Minister Nuri al-Maliki.

The Marxist rebels have repeatedly attacked Turkey from their mountain hideouts in Iraq while Turkey has shelled suspected PKK bases across the border in a conflict that has troubled relations between the two states.

Last month Turkey's parliament extended by one year the government's mandate to strike the PKK in northern Iraq, where Turkish officials estimate about 2,000 fighters are hiding in the mountains.

The PKK, listed as a terrorist group by Ankara and much of the international community, took up arms for self-rule in Turkey's Kurdish-majority southeast in 1984, sparking a conflict that has claimed about 44,000 lives.
