ANKARA, Turkey — Turkey’s military asked the government yesterday to approve attacks on Kurdish rebels in northern Iraq, signaling growing frustration over a lack of action against the guerrillas by Iraqi and American forces.

Such action could put an overstretched U.S. military in the middle of a fight between two crucial partners, the Turks and the Iraqi Kurds, and Washington urged Turkish restraint. A recent surge in Kurdish attacks in southeastern Turkey has increased the pressure on Turkey’s military to act.

“An operation into Iraq is necessary,” General Yasar Buyukanit told reporters.

General Buyukanit said the military already has launched operations against separatists in Turkey’s predominantly Kurdish southeastern region bordering Iraq.

“Our aim is to prevent them from taking positions in the region with the coming of spring,” he said, adding the rebels generally intensify attacks as melting snow opens the mountain passes.

Recent clashes have killed 10 soldiers and 29 guerrillas of the Kurdistan Workers Party, or PKK, General Buyukanit said.

His call steps up pressure on Prime Minister Erdogan to take a harder line against Kurdish guerrillas and their leaders in northern Iraq.

There is strong public support for such a move, but the possibility of high casualties could make the government nervous ahead of elections that must be held by November.

If Mr. Erdogan’s government does ask parliament to approve an incursion, a key consequence would be strained ties with Washington — which fears an offensive would provoke a fierce reaction from Kurdish groups in Iraq that are key allies of U.S. forces.

America also sees Turkey as a crucial ally, strategically straddling Europe and the Middle East.

But some Turks question just how strong their ties should be with Washington if it refuses to side with them against the rebels.
