Geneva, July 11: UN Secretary-General Antonio Guterres said Sudan was on the brink of a “full-scale civil war” as fierce clashes between rival generals continued unabated Sunday in the capital, Khartoum. He warned on Saturday evening that the war between the Sudanese military and a powerful paramilitary force is likely to destabilise the entire region, according to Farhan Haq, deputy spokesperson for the secretary-general. Sudan descended into chaos after months of tension between military chief Gen. Abdel-Fattah Burhan, and his rival Gen. Mohammed Hamdan Dagalo, commander of the paramilitary Rapid Support Forces, exploded into open fighting in mid-April. Health Minister Haitham Mohammed Ibrahim said in televised comments last month that the clashes have killed over 3,000 people and wounded over 6,000 others. The death tally, however, is highly likely to be much higher. More than 2.9 million people have fled their homes to safer areas inside Sudan or crossed into neighbouring countries, according to UN figures.
