In a statement published on its website, the leftist group justified the attack as retaliation for the U.S. policy in Iraq, Syria, Egypt and Libya, according to public broadcaster TRT.
The suicide bomber who killed Friday at least one person and wounded another in the attack on the U.S. embassy is a member of the outlawed leftist group, Turkish Prime Minister Recep Tayyip Erdogan said Friday evening, adding that Turkey would stand united against terrorist attacks.
