Officials and media reports say two British journalists have been detained in Turkey's largest, mainly-Kurdish city, along with their translator.

The Dogan news agency said Vice News correspondent Jake Hanrahan and cameraman Philip Pendlebury were being questioned by anti-terrorism police in Diyarbakir on Friday.

An official from the Diyarbakir governor's office confirmed that the journalists were under police custody for filming without first seeking "media accreditation" from Turkish authorities. He spoke on condition of anonymity because of rules that bar officials from speaking to journalists.

The detentions come amid renewed conflict between Turkey's autonomy-seeking Kurdish rebels and the security forces, which wrecked a 2 1/2-year-old peace process. Some 60 soldiers, police and village guards have been killed since July. Around 90 rebels have also been killed, according to state-run media.
