A police compound in Ankara has been struck by rockets, according to the Turkish interior ministry.
Interior Minister Muammer Guler said two rockets hit two police buildings at the directorate, which is in the suburb of Dikmen.
No one was killed or injured by the attack.
One of the attackers was killed in a shoot-out with police and another was wounded.
Authorities said the perpetrators were members of the Revolutionary People’s Liberation Party-Front (DHKP-C), an outlawed far-left group.
The DHKP-C has been linked to attacks on the US Embassy and the Justice and Development Party (AKP) headquarters in Ankara in recent months.
