Rwanda-backed M23 rebels have taken control of Bukavu, the second largest city in eastern DR Congo, with little resistance from government forces. The situation has led to widespread panic and looting, displacing thousands. President Tshisekedi held a security meeting in Kinshasa, while international leaders, including French President Macron, called for a ceasefire. The conflict is rooted in decades-long ethnic tensions, with fears of regional escalation.
