Mehmet Fatih Taş, the mayor of Diyarbakır’s Kulp district, has been held in police custody for three days over alleged links to an attack by the Kurdistan Workers’ Party (PKK) on September 12, the pro-government Sabah daily reported.

Taş was also removed from office by Turkey’s Interior Ministry over alleged role in the attack.

Along with Taş, four other local politicans from the Peoples’ Democratic Party (HDP), has been detained by Diyarbakır police.

The Diyarbakır Governor’s Office announced that the explosion, which killed seven civilians, was perpetrated by the PKK terrorist organization, although it did not claim the attack.

The Interior ministry appointed Mustafa Gözlet, the Kulp district governor, as a trustee for the mayor’s office.

Turkey in August removed three Kurdish mayors from Diyarbakır, Van and Mardin over alleged terrorist links.
