Turkish warplanes have bombed Kurdistan Workers' Party (PKK) targets along the Iraqi border in southeast Turkey, the country's semi-official Anatolia news agency has said.
The agency said fighter jets from an air force base at Diyarbakir, the main city in the mainly Kurdish southeast, bombed and destroyed several PKK positions on Wednesday.
It said the bombings particularly targeted PKK routes in high mountainous areas.
The raids were said to have been conducted in four provinces, Sirnak and Hakkari, which border Iraq and neighbouring Siirt and Van, which abut the Iranian border.
Bomb attacks
Anatolia said helicopter gunships had also taken part in raids which followed the killing of 12 soldiers in a PKK ambush near the Iraqi border on Sunday.
Turkey has confirmed that eight soldiers are missing following the ambush.
On Tuesday, a pro-Kurdish news agency close to the PKK published what it said were pictures of the troops it said were being held by the group.
Anatolia said suspected PKK fighters had detonated two remote-controlled bombs in the eastern province of Tunceli as soldiers combed a rural area for landmines.
It said security forces had defused other explosive devices found in the area and there had been no casualties.
An operation against the PKK, backed by air cover, is under way in Tunceli, it said.
Meanwhile, Turkey's political and military leaders are meeting in Ankara on Wednesday to consider alternative plans for their next move.
Mike Hanna, Al Jazeera's correspondent in Ankara, said: "No final decision will be made, this is a planning meeting. Alternatives include economic sanctions, closure of the Iraqi border and full-scale military operations.
"The planning of each of these alternatives is being discussed. There is strong domestic pressure on the government... to take concrete action."
Hot pursuit
Earlier on Wednesday, military and security sources said that warplanes had flown up to 20km into Iraqi territory and about 300 ground troops had advanced about 10km over the last three days.
Thirty-four Kurdistan Workers' party fighters were reportedly killed in attacks on their positions between Sunday and late on Tuesday.
"Further 'hot pursuit' raids into northern Iraq can be expected, though none have taken place so far today [Wednesday]," a military official said.
However, another Turkish official told the Associated Press, on condition of anonymity, that there was no Turkish air strike in northern Iraq, but confirmed that shelling had been carried out by artillery units.
The PKK has been fighting for self-rule in southeastern Turkey since 1984 and Ankara has been angered by the group's use of bases in northern Iraq to stage attacks.
Barzani appeal
Reports of the attacks came as the president of Iraq's northern Kurdish region urged the PKK to end its armed campaign against Turkey.
"We call upon the PKK to eliminate violence and armed struggle as a mode of operation," the office of Massoud Barzani, president of the autonomous Kurdish region of Iraq, said in a statement.
"We do not accept in any way, based on our commitment to the Iraqi constitution, the use of Iraqi territories, including the territories of the Kurdistan region, as a base to threaten the security of neighbouring countries."
