Turkey has been buffeted by increased fighting between its military and the outlawed PKK, which has waged a three-decade war for greater Kurdish autonomy.
"Seventeen targets of the separatist terrorists were hit with precision and neutralised" in the Hakkari province on the border with Iran and Iraq, the army said.
In ground fighting, security sources said the PKK attacked a military station in Sirnak, a province adjacent to Hakkari, and killed one soldier in a 20-minute battle.
One PKK fighter was killed in clashes in Bingol province, the local governor's office said.
When violence broke out on Monday
At least nine people were killed in a wave of attacks on Turkish security forces on Monday, mostly in the southeast.
The outlawed Marxist Revolutionary People's Liberation Party-Front, which the government has on occasion linked to the PKK, claimed an attack in Istanbul, and a shooting at the US consulate, which caused no casualties.
A senior police officer in charge of the city's bomb disposal department was killed in clashes that followed a suicide bombing, another attack carried out at a police station on the same day.
While the government blamed the PKK for that attack, it was also claimed by a small leftist group, the People's Defence Units, on its Twitter feed.
