Residents and business owners in eastern Congo’s second largest city are sitting in wait after a night of loud gunfire marking the ongoing advance of Rwanda-backed rebels.

Rwanda-backed rebels captured a second major strategic city in the Democratic Republic of Congo, expanding their dominance over the country’s mineral-rich east amid the widening conflict.

The Rwandan-backed rebels' entry into Bukavu follows their capture of Goma, defying international calls for a ceasefire.
