ISTANBUL (Reuters) - 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announcement, made on Twitter, followed its earlier announcement that the mayors of three major southeastern cities had been replaced by state officials in terrorism-related investigations.
