The Turkish military said Tuesday it carried out renewed airstrikes on positions held by the Kurdistan Workers' Party (PKK) in northern Iraq.
Security forces said several PKK hideouts were destroyed during the Monday operation in Iraq's mountainous Kandil region, where the PKK has its headquarters.
The Turkish military has for months been carrying out a campaign against the banned Kurdish party in the south-east of Turkey.
Security forces are currently involved in clashes with PKK fighters in Nusaybin near the Syrian border and in the Turkish towns of Sirnak and Hakkari.
In Sirnak province's Silopi region, a police officer was killed and four were injured during a PKK grenade attack, DHA news agency reported on Tuesday.
A further policeman, who was injured last week in Diyarbakir, succumbed to his injuries on Tuesday, bringing the number of victims in that attack to eight.
Fighting between the state and Kurdish militants restarted in July after peace talks broke down, ending a two-year ceasefire, amid mutual recriminations. Hundreds have since died, including civilians, while hundreds of thousands have been displaced.
On Monday, Turkish President Recep Tayyip Erdogan repeated that he is not interested in resuming peace talks with the PKK.
