The militant group known as the Kurdistan Freedom Hawks (TAK) on Thursday claimed responsibility for carrying out a suicide bombing in Ankara that left 37 dead, Reuters reported.
TAK has also claimed responsibility for a previous car bombing in the Turkish capital last month that killed 29 people. The group has vowed to keep up its strikes on Turkish security forces.
Ankara has seen three deadly bombing in the space of five months, raising fears about security in Ankara and the rest of Turkey.
In a separate development, Germany announced it had closed its embassy and consular offices in Turkey due to warnings that an attack could be imminent.
The statement released by TAK online described the bombing as revenge for Turkish military operations in the mainly Kurdish southeast that have been underway since a ceasefire with the PKK collapsed in July.
TAK says it has split from PKK, but experts monitoring Kurdish militant groups say the two groups maintain ties.
