"We came with concrete steps, concrete proposals," Jassim said ahead of crisis talks with Turkish officials, expected to begin Friday morning.

The minister heads an 11-member delegation that arrived here Thursday evening seeking to avert a Turkish military operation against bases of the Kurdistan Workers' Party (PKK) in northern Iraq.

The visit follows a trip to Baghdad on Tuesday by Turkish Foreign Minister Ali Babacan, who said after his return that he expected strong action from Iraq.

"I told Baghdad that the delegation must come with concrete proposals, that the visit would be futile otherwise," Babacan said. "We need more than just words."

The delegation includes Iraq's intelligence chief and senior officials from the Iraqi interior and foreign ministries, an Iraqi diplomat told AFP on condition of anonymity.

The delegation also includes representatives of the two major Iraqi Kurdish parties in northern Iraq and a US major about whom no other details were available.

The group settled at the Police Guest House in a southern Ankara suburb, then went to the Iraqi embassy for dinner and were told they would be picked up at 10:00 am (0700 GMT) Friday for talks at a venue that was not revealed, he said.

The diplomat had said earlier that the delegation was scheduled to leave Ankara at midday Friday.

Turkey has stepped up attacks on PKK bases along the Iraqi frontier since parliament last week authorised sending troops to northern Iraq to strike at the separatist outfit's bases.

Washington and Baghdad oppose any incursion.

Tensions rose with a PKK ambush Sunday of a Turkish military patrol that left 12 soldiers dead and eight captured by the rebels.

Iraq has since banned PKK activities on its territory and said it had closed down the offices of the group, considered a terrorist organization by much of the international community.

Turkey's National Security Council, meanwhile, recommended Wednesday that Turkey slap economic sanctions on Kurdish-administered northern Iraq.

The PKK has long been waging a separatist campaign in southeast Turkey that has claimed 37,000 lives since 1984.
