Refugees, surrendering Congolese soldiers and stranded truckers thronged the Rwandan border on Tuesday, hoping to reach safety after rebels captured the nearby Congolese city of Goma and spurred them to flee.

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

Rwanda-backed M23 rebels faced pockets of resistance from army and pro-government militia overnight after entering eastern Congo's largest city Goma in the worst escalation of a conflict that has run for more than a decade.
