By Aidan Lewis(Reuters) - Aid agencies are looking at delivering aid to Sudan on a new route from South Sudan as they struggle to access much of the country, a senior U.N. official said on Monday, nine months into a war that has caused a major humanitarian crisis. More than 7.5 million people have fled their homes, making Sudan the biggest displacement crisis globally, and hunger is rising. Aid agencies lost access to Wad Madani, a former aid hub in the important El Gezira agricultural region southeast of Khartoum, after the RSF seized it from the army last month. Diplomats and aid workers say that the army and officials aligned with it have hampered humanitarian access as both sides pursue their military campaigns. They say the RSF does little to protect aid supplies and workers, and that its troops have been implicated in cases of looting.
