Kurdish militant groups blamed for deadly Ankara blast

Turkey has blamed Kurdish militant groups at home and in neighbouring Syria for a deadly suicide bombing in Ankara, and it vowed strong retaliation, threatening to further complicate the Syria conflict.

The rush hour car-bomb attack on Wednesday evening targeted buses carrying military personnel, killing 28 people and injuring dozens.

It came as Turkey grapples with an array of issues, including renewed fighting with Kurdish rebels, the threat from IS militants and the Syria refugee crisis.
