"The nature of the operations will be harsh tough, and will include no mercy," said Demir. "And also will include more military air bombings. It will also include cross-border operations."
The bulk of the PKK are based in northern Iraq. Two years ago, Turkish forces entered the region in a week-long incursion.
Analysts say Turkey may coordinate its expected operation with Iran, which is already engaged in a major operation against an offshoot of the PKK.
After last month's general-election victory, the prime minister had promised a new constitution that would address many of the Kurdish minority's demands.
But with the hope of peace fading, the fear is growing that Turkey could return to the 1990s - the peak of the conflict with the PKK. That decade saw tens of thousands of people killed, hundreds of thousands more forced from their homes, and Turkey's economy nearly bankrupted.
