Congolese troops pushed back an attempted overnight advance by Rwanda-backed rebels on the eastern city of Goma, two Congolese army sources said on Saturday, after the sound of nearby heavy bombardment rocked the city in the early hours.

Panic spread in Goma on Thursday, with M23 rebels steadily inching closer to the city in eastern Congo as they battle the Congolese army. Bombs were heard going off in the distant outskirts and hundreds of wounded civilians were brought in to the main hospital from nearby towns and villages.

Luggage on their backs, they trudged all Wednesday morning along the road leading to downtown Goma, fleeing the advancing fighters in the eastern Democratic Republic of Congo.
