Two suicide bombers have blown themselves up near the Turkish capital, Ankara, after they were approached by police.
The militants, believed to be a male and female, were suspected of planning to carry out a car bomb attack, the state-run Anadolu news agency reports.
They detonated the devices after they were asked to surrender their weapons.
Police had been acting on a tip-off, Ankara’s governor said, suggesting a link to Kurdish separatists.
Erkan Topaca said police had found the pair hiding at a horse farm in the district of Haymana, just outside the capital.
He said: “The organisation they are connected to is not clear yet but according to information we have received it is highly likely that [the man] is linked to the PKK (Kurdistan Workers Party).”
The BBC says the pair were said to be flying a Turkish flag from their car as cover and a third person is now being sought.
Plastic explosives and ammonium nitrate were found with the vehicle.
