Congo’s leader called on young people to massively enlist in the army to help fight Rwanda-backed rebels who were attempting to seize more territory in the country's east as a crucial meeting of neighbors asked the Congolese government to talk with the rebels.

As an East African bloc urged an immediate ceasefire in eastern Democratic Republic of Congo, Rwandan-backed M23 rebels who seized the city of Goma extended their advance on Wednesday, and Congo said it planned a campaign to recover lost territory.

Residents of Goma reported gunfire and shelling after rebels overran Congolese troops. U.N. officials estimated that more than one million displaced people were now inside the city.
