Separately, the news agency Dicle said on social media that it and the newspaper Azidiye Welat had been targeted in the operation, and that anti-terrorist police had detained 32 journalists and other employees.

Turkey is pushing a relentless offensive against Kurdistan Workers' Party (PKK) rebels and preparing for snap legislative elections on November 1.

The violence has shattered a peace process launched in 2012, which had raised hopes of an end to the PKK's three-decade insurgency in which over 40,000 people have been killed.

In recent weeks, the authorities have carried out a string of arrests of journalists and police have raided a holding company that owns opposition media, sparking criticism from western countries and media watchdogs.
