Six civilian prisoners have been killed and at least 50 wounded in an attack on a US-run detention camp in Iraq, the US military says.
Camp Bucca is located in the far south of Iraq
The attack was aimed at Camp Bucca in the south of the country.
There were no Americans injured or wounded in the incident, according to a US military statement.
Meanwhile, at least 12 Iraqi soldiers were killed and 30 hurt after a suicide car bombing at their base near Hilla, 100km (60 miles) south of Baghdad.
The explosion occurred just after 5pm (1300 GMT), near the gate of the army unit's headquarters.
Camp Bucca is the largest US-run prison facility in Iraq, and has 13,000 of a total of 19,000 detainees held at US facilities in the country.
US military spokesman Lieutenant-Colonel Christopher Garver said the "indirect fire" attack consisted of a number of mortar rounds or rockets fired into Camp Bucca, but he gave no further details.
Earlier, an Iraqi soldier and a civilian were killed when a bomb exploded in a parked car in a mainly Shia district of Baghdad.
In a separate incident, gunmen in a car fired on an army patrol, killing one officer and wounding a second.
