"Turkey will never allow these extremists to realize their dirty aims," Erdogan said in a statement.
At least 11 police officers were martyred when PKK extremists detonated a bomb-laden truck near a checkpoint, the regional governor's office said.
The office also said the blast injured 75 officers and three civilians.
Erdogan said such attacks at a time when Turkey was fighting against extrem threats inside and outside of its borders would only increase country's determination.
"There is no question that our fight with extrem will succeed," he added.
The president also offered his condolences to the families of the martyred officers.
The PKK -- also listed as a extremist organization by the U.S. and the EU -- resumed its 30-year armed campaign against the Turkish state in July 2015.
Since then, more than 600 security personnel have been martyred and more than 7,000 PKK extremists have been killed.
