Sudan President Omar al-Bashir is believed to have stepped down amid nationwide protests contesting his leadership, Al Arabiya TV reports.
Reuters has confirmed the report, citing government sources.
Thousands of protesters have gathered at the army headquarters on Thursday as state media said the army would make an “important statement”.
“We call on our people from across the Khartoum capital and the region around to immediately go to the sit-in area and not leave from there until our next statement is issued,” the Sudanese Professionals Association said.
Al Jazeera’s Hiba Morgan said residents were already celebrating before any announcement was made.
“People are celebrating and pouring in to the sit-in area. Protesters are saying they are very confident that Bashir will resign,” she said.
A sit-in demonstration outside army headquarters, which also houses Bashir’s residence, has entered its sixth day on Thursday.
Its the biggest challenge to Bashir’s three decades of rule.
