In his first public remarks since the M23 rebels advanced into eastern Congo’s largest city, Goma, on Monday, President Tshisekedi late on Wednesday vowed “a vigorous and co-ordinated response” to push back the rebels while reaffirming his commitment to a peaceful resolution.

There are growing international calls for peace talks to end the escalation of violence in the east of the Democratic Republic of Congo. The fate of the economic and trading hub Goma is still unclear. UN officials have said the situation is chaotic with fighting continuing in parts of the city.
