Six soldiers were killed and another was wounded Thursday in a roadside bombing that hit an armored military vehicle in the southeastern Turkish province of Diyarbakir, Turkey's semiofficial Anadolu news agency reported, citing the Turkish General Staff.
Turkey blamed the attack on the PKK -- a Kurdish separatist group that Turkey, the United States and the European Union have designated as a terror organization.
Turkey has been battling the PKK for decades.
The attack on the soldiers was the second deadly blast in two days on Turkish soil that Ankara has attributed to Kurdish groups.
On Wednesday, at least 28 people were killed and 61 injured in an explosion targeting military vehicles in central Ankara.
Ankara says the attack was jointly carried out by a member of the YPG, the Kurdish fighting force in Syria, and PKK members based in Turkey, according to Anadolu.
