Residents of eastern Congo's largest city of Goma greeted the arrival of Rwanda-backed rebels with trepidation on Monday, some staying indoors and others coming out to cheer in what one called a "show" of happiness.

M23 rebels claim they now control the Congolese city of Goma—an act Congo's government described as a 'declaration of war.'

In the capital, Kinshasa, protesters complaining of a lack of international action attacked foreign embassies, including those of the U.S., France and Rwanda.
