Three months later, authorities arrested 21 people there suspected of plotting attacks in the country.
Sanliurfa governor Azim Tuna confirmed to the Anadolu agency that PKK was behind the attack, adding that a nearby housing complex had been "severely damaged".
"This terrorist attack was carried out against not only the judiciary but also our law, our justice, our nation, and our unity. No terrorist organization or terrorist attack will deter Turkey's fight against terror", Bozdağ posted on Twitter.
Turkey has been hit by a series of violent attacks since the summer of 2015, which were blamed on the Islamic State group or Kurdish militants.
