Turkey’s Prime Minister has said an outlawed Marxist group was responsible for the suicide bombing in front of the US Embassy in Ankara.
A suicide bomber and a Turkish guard have been killed in the attack.
Recep Tayyip Erdogan said on Turkey’s HaberTurk television that the attack is the work of the Revolutionary People’s Liberation Party-Front, or DHKP-C.
The group has been designated a terrorist organisation by the United States and the European Union.
Mr Erdogan said: “It is my principle to speak only after receiving the final result, but I can say clearly that it is DHKP-C.”
