Car bomb kills 4 in northern Iraqi city of Mosul

Baghdad: A car bomb exploded on Wednesday in the volatile northern Iraqi city of Mosul, killing four civilians and wounding three others, police said.

A police officer in Ninevah province said the bomb went off in a parked car in a predominantly Sunni area of this city, where violence has continued against Christians and others despite months of US and Iraqi military operations to chase out extremists.

In Baghdad, meanwhile, police and hospital officials said three separate blasts killed a sick man being transported in an ambulance and wounded 11 others.

The bombings highlight the continued security challenges in Iraq amid a national debate over the future role of American troops in the country.
