Turkish fighter jets carried out a new barrage of air strikes against PKK terrorists in northern Iraq overnight, the army said.

A police officer was also killed during an operation against PKK terrorists in Turkey's southeastern Diyarbakır province on Wednesday.

The air bombardments "destroyed" targets of the PKK in several northern Iraqi regions including its main stronghold on Qandil mountain, the army said in a statement.

In a separate incident, one policeman was killed after coming under fire from snipers as he was trying to defuse an explosive device in the Sur district of Diyarbakır province, which has been under a military curfew for eight days.

The PKK -- blacklisted as a terrorist organization by Turkey, EU and the US -- has carried out terrorist attacks, killing dozens of police and soldiers, as well as civilians almost on a daily basis.

The violence has destroyed hopes of fresh talks to end a conflict that has claimed tens of thousands of lives since 1984.

The PKK resumed its armed campaign in late July.

Since then, around 195 members of the security forces have been martyred while more than 1,700 terrorists have been killed, according to official figures.
