Two Turkish gendarmeries were martyred in eastern Turkey in a clash with terrorists, the Interior Ministry said on Saturday.
In a statement, the ministry said that four gendarmeries were also injured in the eastern Bitlis province during an anti-terror operation in the region.
The operation is still ongoing, the statement added.
In its more than 30-year terror campaign against Turkey, the PKK -- listed as a terrorist organization by Turkey, the US and the European Union -- has been responsible for the deaths of nearly 40,000 people including women, children, and infants.
