Officials say a prison break in central Iraq has killed 10 guards and 2 inmates and that many prisoners, including suspected al-Qaida fighters, escaped after hours-long clashes with security forces inside the facility, according to AP.

A spokesman in Salahuddin province says several convicts broke into a prison storeroom in Tikrit late on Thursday, Sept 27 night, seized weapons and overpowered prison guards.

Spokesman Mohammed al-Assi says several hours of clashes followed and that scores of prisoners had escaped by Friday morning when security troops regained control of the prison. Tikrit is 130 kilometres north of Baghdad.

A provincial health official, Raed Ibrahim, confirmed that 12 died in the violence.

Prison breaks are common in Iraq and are a big embarrassment to the country's government.
