Turkish warplanes have bombed Kurdish separatist militants hiding in northern Iraq.
In a brief statement on the Turkish military's website, it said strikes had hit the Zab and Hakurk areas, targeting caves and hideouts belonging to the "separatist terror organisation", a term used by the government to describe the Kurdistan Workers Party (PKK).
The general staff did not say whether anyone was injured in the bombing raids, which were carried out on Saturday night, but there was no damage or injuries on the Turkish side.
Turkey has stepped up attacks on the PKK in recent months following a number of raids and ambushes on Turkish forces inside Turkey.
The raids have fuelled tension between the two parties and have triggered protests in northern Iraq and in Turkey's predominantly Kurdish southeast.
Relations between Ankara and Iraq's central government in Baghdad have also become strained in recent weeks, with Iraq accusing turkey of meddling and the former responding by suggesting Iraq may be heading for a sectarian war.
The three-decade-old conflict has seen over 40,000 people killed since the PKK took up arms for Kurdish self-rule in 1984.
The group is considered a terrorist organisation by Turkey, the United States and the European Union.
