Turkish bomb-disposal experts disabled an explosive device in a vehicle found overnight near a government building in southeast Turkey, security sources on Friday as a recent spate of bomb attacks prompted security warnings in major cities.
The vehicle was found with 150 kg (331 lb) of explosives in the town of Hani in Turkey's southeastern Diyarbakir Province, the sources said. Police examined security cameras in the area as part of the investigation.
PKK-affiliate terrorist group TAK on Thursday claimed a suicide bombing in Ankara that killed 35 people on March 13 and warned of further attacks.
Last Sunday's suicide bombing was the second in a month in the heart of Ankara claimed by the TAK terrorist group.
On Feb. 17, a suicide attacker set off a car bomb near the Turkish General Staff and parliament buildings in Ankara, killing 29 people and wounding 81 others.
TAK claimed responsibility for the attack several days later.
Turkey has long been confronted with armed attacks in its southeastern and eastern regions by the PKK.
The PKK resumed its 30-year armed campaign against the Turkish state in late July 2015 after unilaterally ending a two-and-a-half-year-long ceasefire with the government and threatening Turkey with further attacks.
Since then, Turkish Security Forces have killed more than 1,500 PKK terrorists in security operations, while more than 300 people including security officers and civilians have died as a consequence of PKK terror attacks in Turkey.
