It's a remarkable turnaround in this year and a half long rebellion. In November United Nations troops had stood by powerless as rebel fighters briefly captured the regional capital Goma. The UN had pledged to protect the city and blamed the defeat on what they said was military backing from Rwanda.__________________________But injection of fresh peacekeepers earlier this year with a stronger mandate to actively take the fight to the rebels appeared to have turned the tide. 长达一年半的叛乱形势终于出现转机.去年11月时,联合国军队还对于迅速占领地区首府戈马的叛军无能为力.联合国曾承诺保护该地区,并将失败归责于卢旺达政府对叛军的支持._____________________________今年早些时候,维和部队增援军被授权积极全力打击叛军,局面似乎才得以扭转.
