The suicide bomber who carried out the deadly attack in Ankara on Sunday was identified as a member of the outlawed Kurdish Workers' Party (PKK), Turkey's Interior Ministry said on Tuesday.
The PKK member was Seher Cagla Demir and she was born in 1992 in the province of Kars in eastern Turkey, the ministry was quoted by Xinhua as saying.
Demir joined the PKK in 2013 and later received training with the People's Protection Units in Syria.
The car bomb in Ankara's central Kizilay neighbourhood on Sunday evening hit a major public transportation hub, killing 37 people and injuring over 100 others.
Since a ceasefire between the government and the PKK collapsed last July, Turkish security forces have been conducting a major campaign against the group in the southeast of the country.
More than 260 members of Turkish security forces and thousands of PKK members have been killed inside Turkey and in northern Iraq.
