Four policemen have been martyred in a bomb attack, suspected to have been carried out by Kurdistan Workers’ Party (PKK) militants in the southeastern province of Mardin on Thursday, local police sources said.
Police said the bomb was planted near an overpass and was detonated when a car carrying the policemen passed through in Mardin's Dargecit district.
The bodies were taken to Mardin State Hospital.
Operations against the PKK -- listed as a terrorist group by Turkey, the EU and the U.S. -- came after it renewed attacks on Turkish security forces following the July 20 Suruc bombing that killed dozens of people.
The fighting between the PKK and the security forces had seen a fragile lull for a two-and-a-half year period from early 2013 in what is publicly known as the "solution process" in an attempt to end the decades-long conflict.
