The Kurdistan Freedom Hawks (TAK), a Kurdish militant group, has claimed responsibility for the Ankara bombing that killed 28 people this week, according to its website. It said the attack was in retaliation for Ankara's military operation in Turkey's southeast.

The TAK, which is a splinter group of the outlawed Kurdistan Workers' Party (PKK), vowed to continue its attacks, Reuters reported, citing the group's statement published on Friday.

It identified the perpetrator of the Ankara bombing as a 26-year-old Turkish national born in the eastern city of Van.

The militant group operates in Turkey and northern Iraq and is regarded as a terrorist organization by Ankara and the US. It has claimed responsibility for a number of attacks since 2004. The latest one was the December mortar attack at Istanbul's Sabiha Gokcen airport that killed one man and damaged five aircraft.

The TAK has said that it severed links with the PKK. The latter, in turn, has reportedly denied having any control over the TAK.
