Three members of the Kurdistan Workers' Party (PKK) were killed in clashes with Turkish security forces in the southeastern Sirnak province.

Seven persons, including two Turkish policemen, were also injured.

A police officer was seriously injured, a statement by the governor office reported.

The clashes erupted when PKK militants attacked the security forces using homemade explosives, long-range missiles and landmines, the statement added.

The violence comes amid rising tension between the Turkish security forces and the PKK, who are designated as a terrorist organization by Ankara.

Approximately 1,300 individuals suspected of involvement with the PKK have been arrested following a suicide bombing on a rally in Suruc, which killed 132 people in July.

The attack, among the worst experienced in Turkey, saw the government pledge to join the US-led coalition against Daesh, but also the resumption of a bombing campaign against PKK positions along the Iraqi and Syrian border.
