At least 30 prisoners and 10 guards have been killed in a prison break in Iraq, as more than 50 other inmates escaped, officials and police say.
The Islamic State (IS) militant group says it was behind the attack on the jail in Khalis, north-east of Baghdad.
But officials blame the incident on a prison riot in which inmates tried to seize weapons and managed to break out.
Iraq has seen a number of prison breaks. Many have been caused by militants seeking to free comrades.
Nine of the inmates who got away in the latest incident were being held on terrorism charges, including IS members. The rest, officials said, were common criminals.
