Turkish warplanes carried out a new wave of air strikes against Kurdistan Workers' Party (PKK) members in the southeast, killing 13 fighters overnight, the army said Monday.

13 fighters were killed in the remote Hakkari province, on the border with Iraq, the general staff said in a statement on its website.

Meanwhile in Istanbul, police detained at least 13 suspected PKK members on Monday after receiving intelligence that they were planning to attack shops and government buildings in the city with Molotov cocktails, Dogan news agency said.

Ankara has used air power and ground forces in a self-declared "anti-terror" operation to try to cripple the PKK in its strongholds in southeastern Turkey and northern Iraq since a two-year ceasefire broke down in July.
