Sudanese took to the streets in the capital of Khartoum and elsewhere across the country for mass protests Sunday against an October military takeover and a subsequent deal that reinstated Prime Minister Abdalla Hamdok, but sidelined the movement.

The demonstrations marked the third anniversary of the uprising that eventually forced the military removal of longtime autocrat Omar al-Bashir and his Islamist government in April 2019.

Sudan then followed a fragile path toward democracy and ruled by a joint military-civilian government. The October 25 coup has rattled the transition and led to relentless street protests.

Video footage circulated online purported to show protesters marching in the streets of Khartoum and its twin city of Omdurman on Sunday.

Protesters were seen waving the Sudanese flag and white ones with printed images of those killed in the uprising and ensuing protests.

Ahead of the demonstrations, Sudan’s authorities tightened security across the capital, barricading government and military buildings to prevent protesters from reaching the military’s headquarters and the presidential palace.

They also blocked major roads and bridges linking Khartoum and Omdurman across the Nile River.
