At least 21 people have lost their lives in fresh clashes between Turkish army and militants of the outlawed Kurdistan Workers' Party (PKK) in the volatile southeastern Turkey.
The overnight clashes broke out after PKK militants ambushed a military convoy in Semdinli town of Hakkari province, bordering with Iraq.
Security forces said that sixteen PKK members and five Turkish soldiers were killed in the violence.
Sources say the clashes are still ongoing in the region.
The incident came days after nine people, four of them children, were killed and dozens more wounded in a car bomb attack in the southeastern province of Gaziantep.
Turkish President Abdullah Gul and Prime Minister Recep Tayyip Erdogan also attended a funeral ceremony for the victims of the Monday attack.
Over 40,000 people have lost their lives since the PKK launched its armed campaign against Ankara in 1984.
