Rwanda-backed rebels have captured two major cities in Congo’s mineral-rich east after a major escalation in their yearslong fighting against Congolese forces.

Rwandan-backed M23 rebels have entered Bukavu, the second-largest city in the eastern Democratic Republic of Congo, seizing the regional governor's office. Some people lined the streets to clap and cheer the fighters as they marched and drove into the city centre without resistance.

Panic swept through eastern Congo’s second-largest city on Saturday as residents fled by the thousands, scrambling to escape the looming advance of Rwanda-backed rebels. Amid chaos and looting, Bukavu braced for what comes next.
