Russian President Vladimir Putin's spokesman Dmitry Peskov has said they hope that the situation in Sudan will soon go back on to "a constitutional course".
"We are very closely monitoring the situation. We hope that, firstly, there will not be an escalation of the situation that could lead to human casualties. And we expect that in the very near future the situation will return to a constitutional course," Mr Peskov told journalists, as reported by Russian news agency Interfax.
He added that the Kremlin viewed the situation as an internal affair of Sudan.
"Of course, regardless of what is happening, what is happening is an internal affair of Sudan and should be decided by the Sudanese themselves. Whatever the outcome, Russian-Sudanese relations will be a constant in the foreign policy of Sudan," Mr Peskov said.
A Sudanese woman involved in the protests, Hiba Ali, spoke to the BBC from Khartoum.
Quote MessageEverybody's out on the streets right now. The suspense is killing us. People are waiting for the official statement from the army. It's clear that there are some last-minute negotiations about the transition of power."
She also said there was no sign on the streets of police or security forces loyal to President Bashir - only army personnel, thought to be on the side of the protesters, could be seen.
Quote MessageWhat we can see on the ground right now are the rapid support forces and the military officers who are roaming the streets and protecting the premises of the army headquarters as well as protecting the protesters, as they've been doing for the past four days of strikes. I don't see any sign of the police who are in blue uniform or the popular forces who are under the command of the national intelligence security service."
She said removing President Bashir would not be enough - the protesters wanted a civilian democracy.
Quote MessageWhat the people are calling for is freedom, justice and equality. It's not just about (President) Bashir stepping down. It's also about the whole regime going down and everything that came with it and 30 years of oppression. So what we want is a transition to a democracy. We want a civilian government and a handover of authority and power to the people."
A protester has been messaging the BBC’s Charlotte Attwood from outside the army headquarters. He wrote: “It's intense right now, as people wait for the radio speech."
The protesters are waiting for a speech promised by the army more than seven hours ago - but state radio is currently only playing marching music.
There is speculation that the military could force President Omar al-Bashir to quit.

A protester, Yassir Hohle, spoke to the BBC as he joined the demonstration on its way towards the army headquarters in Khartoum.
"I see all the people, all the people in Sudan happy about this dictator's end," he said. "It feels like the whole of Khartoum is here. People are happy, they're partying, they're crying, government down, government down."
The group spearheading the protests in Sudan have said they refuse to accept anyone from the current regime in a new government, as they await an announcement promised by the army.
The Sudanese Professionals Association laid down the demands on their website earlier today, external:
Quote MessageAfter our struggle and perseverance for more than four months, filled with blood, sweat and tears, we urge the masses to mobilise, continue and enhance the sit-ins.
Quote MessageWe assert that the people of Sudan will not accept anything less than a civil transitional authority composed of a patriotic group of experts who were not involved with the tyrannical regime.
Quote MessageThe leadership of our people’s armed forces ought to handover power to the people, according to what was expressed in the declaration of freedom and change."
The army promised more than six hours ago that they would make an important statement - which has led to speculation that they may intend to announce that President Omar al-Bashir will stand down.

The evolving relationship between the protesters and the military is likely to determine the fate of the uprising against President Omar al-Bashir.
These fresh images from the streets of Khartoum provide some clues about that relationship.
Here, soldiers and protesters can be seen in close proximity, facing off outside official buildings. But the mood of the confrontation seems to be more convivial than hostile.

The group at the forefront of the demonstrations against President Omar al-Bashir urged the people "not to attack" government and private properties, reports AFP news agency.
"We are calling on our people to control themselves and not to attack anybody or government and private properties," the Alliance for Freedom and Change is quoted as saying in a statement.
"Anyone found doing this will be punished by law. Our revolution is peaceful, peaceful, peaceful," it adds.
They are still waiting for a key announcement from the army. It was promised more than six hours ago and is expected to be announced on State radio, which you can listen to online., external
