An outlawed leftist group might be behind the twin attacks in Ankara late Tuesday, Turkey\'s deputy prime minister said Wednesday.Clues suggested that the outlawed Revolutionary People\'s Liberation Party/Front (DHKP/C) might have carried out Tuesday two attacks against the justice ministry and headquarters of the ruling Justice and Development Party, leaving two people wounded, said Bulent Arinc.The group has suffered a setback in recent operations of Turkish security forces, Arinc said, accusing the attacks of hampering the government-launched peace talks, which are expected to solve the decades-long Kurdish issue.The DHKP/C has claimed responsibility for a suicide bombing against the U.S. embassy in Ankara in February.Local media reported earlier that two suspects have been detained in connection with the attacks.
