Videos posted on social media show General Fattah al-Burhan. He is seen walking among soldiers in central Khartoum.
He has been in hiding since the beginning of the month, when fighting broke out in the city. The two sides have been fighting over control of the city's old industrial zone. The city has been the scene of violent clashes since the start of the year, with more than 100 people killed and thousands injured. The fighting is now in its sixth week, and the city is in the grip of a humanitarian crisis.
