United Nations Secretary-General António Guterres called for an immediate halt to fighting in Sudan on Thursday and appealed for a three-day cease-fire to mark the end of the Muslim holy month of Ramadan to enable trapped civilians to seek safety and supplies. Clashes have entered their seventh day in Sudan on Friday. More than 413 people have been killed due to fighting in the capital Khartoum and several other states, including Darfur. Another 3,551 people have been injured.
