Thousands of protesters have filled the streets of Khartoum calling for an end to the country's military council.Many had travelled in from across Sudan to take part in the "million-strong march" for civilian rule.
It comes despite the resignation of three controversial figures from the ruling Transitional Military Council - one of the protesters' key demands.
The three generals were seen as staunch Islamists and allies of deposed President Omar al-Bashir.
"We are in the middle of a historic moment. Any divisions will break the back of Sudan," one protester told the BBC.
"The military council is simply wasting time hoping that we will get disappointed and go home," said another.
"We have been here for four months already. We can wait for 100 years until we get what we want."The enormous rally has been organised by an umbrella group of protesters called the Alliance for Freedom and Change.
Many gathered outside of Sudan's army headquarters, while earlier demonstrations were held outside Egypt's embassy.
The fresh protests on Thursday come soon after a late-night meeting between the military council and leaders of the Alliance.
