"Turkey will develop solutions... of its own volition. The platform for discussing these is obvious and they are the cabinet and the national security council," Davutoglu said in remarks published Tuesday in several newspapers.

"We should not look for other platforms," he added in response to a question on whether proposals expected from Abdullah Ocalan, the jailed leader of the outlawed Kurdistan Workers' Party (PKK), would factor in Ankara's own efforts to resolve the conflict.

Last week, the PKK announced that Ocalan, serving a life sentence on a prison island, would announce in August a "roadmap for a democratic solution" regarding the PKK's 25-year armed campaign against the Ankara government.

The rebels also said they had extended a unilateral truce by six weeks until September 1 in anticipation of their leader's proposals.

Ankara rejects dialogue with the PKK, which it lists as a terrorist organisation, has never formally recognised PKK truces and the army has continued to pursue the rebels.

Also Tuesday, a soldier was killed when a homemade explosive device, blamed on the PKK, went off in a mountainous area in Sirnak province, security sources said.

The soldier was part of a military unit that was on an operation to hunt down rebels holed up in the region.

The PKK took up arms in 1984 for self-rule in Turkey's Kurdish majority southeast, sparking a conflict that has claimed some 45,000 lives.
