Residents of Goma reported gunfire and shelling after rebels overran Congolese troops. U.N. officials estimated that more than 1 million displaced people were now inside the city.

Goma, Congo — Residents in eastern Congo’s largest city, Goma, were fleeing on Monday after Rwanda-backed rebels claimed to have captured the regional hub from Congolese forces as fighting escalated despite calls from the U.N. Security Council for the insurgents to withdraw.

Residents shared videos of M23 rebels patrolling Goma's main streets following a lightning advance against the Congolese army on Sunday that saw tens of thousands of people fleeing neighbouring towns.
