Some 60 people were killed Sunday in a bloody day of sectarian violence in the Iraqi capital.

Masked Shi'ite gunmen went on a rampage in a Sunni Muslim area of Baghdad, killing at least 42 people. Police say the gunmen set up fake checkpoints and also moved through the city's Jihad district, checking identity papers and killing people with typically Sunni names.

Police say two car bombs went off hours later outside a Shi'ite mosque in central Baghdad, killing 17 people and wounding more than 38 others.

Meanwhile, the U.S. military says four more U.S. soldiers were charged with rape and murder in the March attack on an Iraqi family - the latest in a series of allegations of mistreatment of Iraqi civilians by U.S. forces.

A statement says the soldiers are suspected of conspiring with former U.S. Army Private Steven Green. He pleaded not guilty last week in a U.S. court to charges he raped and murdered a young Iraqi woman and killed three members of her family.

Iraqi Prime Minister Nouri al-Maliki has called for an independent inquiry into the allegations.

Separately, the U.S. military says a coalition soldier died in a non-combat-related incident Sunday.
