At least 21 people have been killed and 35 wounded in a suicide car-bomb attack in Baghdad late on July 22.
Police said the suicide bomber drove his explosive-laden car into a police checkpoint at the entrance to Baghdad's Khazimiyah district.
Among the dead were seven policemen manning the post.
Police said there was a long line of cars at the checkpoint at the time of the attack.
Many were heading to the Imam al-Khadim Shrine in the lead-up to the Eid feast commemorating the end of Ramadan.
Baghdad has been on edge since the Sunni militant offensive led by the Islamic State extremist group seized the northern city of Mosul, vowing to push south to the capital.
The city has seen several small-scale bombings in recent weeks.
