Humanitarian fears mount as airport is last obstacle before city of Bukavu and its population of about 1m people
Rebels from the Rwandan-backed M23 group have seized the strategically important airport serving Bukavu, the capital of South Kivu province in the Democratic Republic of the Congo, following a rapid advance south in recent days.
The airport in the town of Kavumu, where Congolese troops had been positioned, is the last military obstacle to the rebels before Bukavu, a city of about a million people 17 miles (27km) to the south.
