A Turkish leftist group claimed responsibility on Saturday for a suicide bomb attack on the U.S. embassy and accused Washington of using Turkey as its "slave", according to a statement posted on the internet.

The Revolutionary People's Liberation Army-Front (DHKP-C) said it carried out Friday's attack, in which a suicide bomber detonated explosives strapped to his body at the embassy in Ankara, killing himself and a Turkish security guard.

In a statement on "The People's Cry" website, the DHKP-C, which is listed as terrorist organization by the United States and Turkey, warned Turkish Prime Minister Tayyip Erdogan he too was a target.
