An explosion has hit an oil pipeline in south-east Turkey, killing two people and wounded one other, reports say.
The Kurdish separatist group, the PKK, is suspected to have detonated a mine next to the pipeline, the semi-official Anatolia news agency reported.
The victims were travelling in two vehicles which caught fire as they passed the blaze, reports said.
The pipeline carries oil from Kirkuk in northern Iraq to the port of Ceyhan on Turkey's Mediterranean coast.
Reports say the explosion happened in Sirnak province, which borders northern Iraq and Syria.
Oil flow was stopped while firefighters tackled the blaze, officials said.
The Turkish NTV news channel reported that the explosive was remote-controlled, but this was not confirmed.
PKK guerrillas have carried out previous attacks on the pipeline - most recently last month. The last explosion disrupted oil supplies for several days.
The PKK has waged a 26-year insurgency against the Turkish state. It is designated a terrorist organisation by Turkey, as well as the EU and US
