Turkish police have detained 418 people in 29 provinces in an investigation targeting suspects with links to the Kurdistan Workers Party (PKK) militant group, the Interior Ministry said on Monday.
The ministry announcement on Twitter followed its earlier statement that the mayors of three major southeastern cities had been replaced by state officials in terrorism-related investigations.
The pro-Kurdish party mayors of Diyarbakir, Van and Mardin were replaced on Monday, and state governors were appointed in their place.
The mayors were accused of various crimes including membership of a terrorist organization and spreading terrorist group propaganda, Reuters said.
