Rwanda-backed rebels who captured eastern Congo's largest city said Thursday they want to take their fight to the far-off capital, Kinshasa, while Congo’s president called for a massive military mobilization to resist the rebellion and his defense minister rejected calls for dialogue.

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

Rebels backed by Rwanda captured more towns in eastern Congo as fighters moved beyond the key city of Goma in an apparent attempt to expand their control in the conflict-battered region
