Goma — Renewed fighting has broken out around Goma, the capital of North Kivu province, close to the Democratic Republic of Congo's border with Rwanda.
And UN peacekeepers are taking a more combative role as fighting escalates in the DR Congo, Al Jazeera reported on Tuesday, August 27
Its elite intervention brigade, which has been given a robust mandate to take on armed groups, has been drawn into the fight, changing the dynamic of the conflict in DRC's troubled east and raising questions about the UN's aggressive new military mandate.
M23 rebel fighters briefly seized the city in November, but withdrew in return for a promise of peace talks, however, those talks in Uganda have made little headway.
And they are now being accused of rocket and mortar attacks on Goma, and shelling neighbouring Rwanda. The group blames the cross-border attacks on the Congolese army.
M23 is the largest rebel group in DR Congo. It takes its name from an agreement on March 23, 2009 which integrated fighters into the DRC's national army. But in April last year, many deserted the group, complaining of discrimination and poor treatment.
However, there are an estimated 2,000 fighters in the movement. In November, they dealt a serious blow to the credibility of what is the world's largest peacekeeping force, marching past UN soldiers to seize Goma.
That seems unlikely to happen again as the new UN Intervention Brigade, set up last month, is authorised to carry out what are described as 'targeted offensive operations', meaning they can fire first.
UN peacekeepers gave M23 rebels 48 hours to lay down their arms at the beginning of August but that deadline was ignored.
Tensions are now being strained further, after UN peacekeepers from Uruguay were accused of shooting dead two people during protests over the latest fighting.
It is all serving to raise the stakes for the UN peacekeeping mission, and raising concerns that its new, more offensive mandate could backfire.
