WASHINGTON - Satellite images taken at night show heavily Sunni Arab neighborhoods of Baghdad began emptying before a U.S. troop surge in 2007, graphic evidence of ethnic cleansing that preceded a drop in violence, according to a report published on Friday.
The images support the view of international refugee organizations and Iraq experts that a major population shift was a key factor in the decline in sectarian violence, particularly in the Iraqi capital, the epicenter of the bloodletting in which hundreds of thousands were killed.
Minority Sunni Arabs were driven out of many neighborhoods by Shi'ite militants enraged by the bombing of the Samarra mosque in February 2006. The bombing, blamed on the Sunni militant group al Qaeda, sparked a wave of sectarian violence.
