Ankara, Turkey (CNN) 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.Six Turkish soldiers killed in roadside blast, a day after bomb kills 28 people in AnkaraTurkey responded to attacks with airstrikes targeting Kurdish separatist group in IraqTurkish Prime Minister: Member of Syrian Kurdish force YPG carried out Ankara attack
