Congo's M23 rebels take control of Goma airport, embassies attacked in capital

Rebels seized the airport of east Congo's largest city Goma on Tuesday, potentially cutting off the main route for aid to reach hundreds of thousands of displaced people, after capturing the city in an offensive that left dead bodies lying in the streets.

M23 fighters marched into Goma on Monday in the worst escalation since 2012 of a three-decade conflict rooted in the long fallout from the Rwandan genocide and the struggle for control of Congo's abundant mineral resources.

In the Congolese capital Kinshasa, 1,600 km west of Goma, protesters attacked a U.N. compound and embassies including those of Rwanda, France and the United States, expressing anger at what they said was foreign interference. Looters ransacked the embassy of Kenya.

Goma is a major hub for people displaced by fighting elsewhere in eastern Congo and aid groups seeking to assist them.

The fighting has sent thousands of people streaming out of the city including some who had recently sought refuge there from M23's offensive since the start of the year.

Just across the border in Rwanda, trucks were unloading large numbers of people fleeing Goma with their children and bundles of possessions wrapped in pieces of fabric.

Democratic Republic of Congo's government and the head of U.N. peacekeeping have said Rwandan troops were present in Goma, backing up their M23 allies.

Rwanda has said it is defending itself against the threat from Congolese militias, without directly commenting on whether its troops have crossed the border.

Goma residents and U.N. sources said dozens of troops had surrendered, but some soldiers and pro-government militiamen were holding out. People in several neighbourhoods reported small arms fire and some loud explosions on Tuesday morning.

"I have heard the crackle of gunfire from midnight until now ... it is coming from near the airport," an elderly woman in Goma's northern Majengo neighbourhood, close to the airport, told Reuters by phone.

Much of the fighting was concentrated around the airport, and by Tuesday afternoon several diplomatic and security sources said the M23 rebels had taken full control of it, putting them in charge of a vital link to the outside world.

"It was through the airport that the U.N., the humanitarian groups, the peacekeepers and even the Congolese army were getting supplies in," said Congo researcher Christoph Vogel, adding that there was no viable access by road or by boat on Lake Kivu.

Jens Laerke, spokesperson for the U.N. humanitarian office (OCHA), told a briefing in Geneva colleagues had reported "heavy small arms fire and mortar fire across the city and the presence of many dead bodies in the streets".

"We have reports of rapes committed by fighters, looting of property ... and humanitarian health facilities being hit," he added. Other international aid officials described hospitals overwhelmed with wounded being treated in hallways.

Francois Moreillon, head of the International Committee of the Red Cross in Congo, told Reuters a medicine warehouse had been looted, and he was concerned about a laboratory where dangerous germs including ebola were kept.

"Should it be hit in any way by shells which could affect the integrity of the structure, this could potentially allow germs to escape, representing a major public health issue well beyond the borders of the DRC," he said.

In Kinshasa, angry crowds chanted anti-Rwanda slogans and attacked embassies of several countries seen as favourable to Rwanda, setting fire to tyres and buildings. The police fired tear gas to disperse them.

"What Rwanda is doing is with the complicity of France, the U.S. and Belgium. The Congolese people are fed up. How many times do we have to die?" said protester Joseph Ngoy.

The Rwandan, French, U.S., Ugandan, Kenyan, Dutch and Belgian embassies were targeted. Videos posted online and verified by Reuters showed dozens of people looting the Kenyan embassy, while others showed looting had spread to other locations including a supermarket.

M23 is the latest in a string of ethnic Tutsi-led, Rwandan-backed insurgencies that have brought tumult to Congo since the aftermath of the genocide in Rwanda 30 years ago, when Hutu extremists killed Tutsis and moderate Hutus, and then were toppled by the Tutsi-led forces that still govern Rwanda.

Rwanda says some of the ousted perpetrators have been sheltering in Congo since the genocide, forming militias with alliances with the Congolese government, and pose a threat to Congolese Tutsis and Rwanda itself.

Congo rejects Rwanda's complaints, and says Rwanda has used its proxy militias to control and loot lucrative minerals such as coltan, which is used in smartphones.

The U.N. and global powers fear the conflict could spiral into a regional war, akin to those of 1996-1997 and 1998-2003 that killed millions, mostly from hunger and disease.

Corneille Nangaa, leader of the Congo River Alliance that includes the M23, has suggested the rebels' aim is to replace President Felix Tshisekedi and his government in the capital.

U.N. peacekeepers have been caught up in the fighting. South Africa said three of its soldiers were killed in crossfire between government troops and rebels and a fourth had succumbed to wounds from earlier fighting, bringing the number of its fatalities in the past week to 13.
