A suicide bomber has struck a police checkpoint in the Iraqi capital, Baghdad, killing and wounding many.

Casualty figures in the July 24 attack remain unclear, with agencies quoting Iraqi officials as saying between six and 12 people were killed, with as many as two dozen injured.

A medical official told the AP news agency that three of the dead were police officers.

The Islamic State terrorist organization issued a statement claiming responsibility for the attack, which happened at an entrance to the primarily Shi'ite district of Kadhimiyah.

The Islamic State terrorist organization claimed responsibility for a blast in the capital on July 3 that left more than 290 dead. It also took responsibility for an attack on a Shi'ite shrine in Balad a few days later that left 40 dead.
