Turkish Prime Minister Recep Tayyip Erdogan said Friday that Turkish security forces will not stop conducting military operations unless PKK lay down arms.

"Security forces carry out operations only when it is necessary. And when weapons are laid down operations will certainly end," Erdogan told reporters in a press conference upon his arrival in the Turkish capital, Ankara, from a visit to Mexico and Brazil.

A latest attack on Tuesday on a military outpost in southeast Turkey killed 8 Turkish troops and wounded 16 others.

Erdogan also said Turkey would continue its struggle against terrorism with determination.
