ANKARA, Turkey (AP) — Turkey's state-run news agency says the mayor of Turkey's largest Kurdish-populated city has been detained for questioning as part of a "terrorism" investigation. A second local pro-Kurdish politician also was detained.

The Anadolu Agency reported that anti-terrorism police took Diyarbakir mayor Gultan Kisanak into custody late Tuesday at the city's airport. The second politician, Firat Anli, was held at his home.

The agency cited an ongoing investigation into the outlawed Kurdistan Workers' Party, or PKK, as the reason for their detentions, without providing further details.

Kisanak is a member of Turkey's legal pro-Kurdish Peoples Democratic Party, which the government accuses of being the political wing of the PKK. The party denies the accusation.

Earlier Tuesday, she had testified in front of a parliamentary committee investigating Turkey's failed July 15 military coup.
