ANKARA

 At least 54 PKK terrorists have been killed in ongoing operations in Turkey’s southeastern Sirnak province within the last 72 hours, a security official said Friday. 

The official, speaking on condition of anonymity, told Anadolu Agency that security forces had been operating in Cizre and Silopi districts.

A curfew was in placed on Cizre and Silopi on Monday. Many citizens have reportedly left the district before the curfew was imposed.

The PKK -- also considered a terrorist organization by the U.S. and EU -- resumed its armed campaign in late July. Since then more than 200 members of the security forces have been martyred and around 1,700 PKK terrorists killed.
