Over one billion pounds has been pledged at an international summit in Germany to fund humanitarian assistance to Sudan, where a brutal but largely overlooked civil war enters its fourth year today. The conflict, which has been described as the world's largest humanitarian challenge, has already led to the displacement of 13 million people. The International Criminal Court is investigating potential war crimes, particularly in Darfur where 6,000 people are believed to have been killed in just 3 days last October. #Sudan #Darfur #Conflict #Displacement #C4news
