Live: Latest on Sudan crackdown
Live Updates
The death toll from Sudan's recent violence does not exceed 46, state news agency SUNA reported early on Thursday citing a health ministry official.
Opposition doctors said 40 bodies that had been pulled out of the Nile on Tuesday were among the 108 killed.
The bodies were taken to an unknown destination by pickup trucks belonging to the paramilitary Rapid Support Forces, the medics said. Reuters was not immediately able to verify the report.
The military council said on Twitter that some Rapid Support Forces members had been attacked and that people had put on their uniforms to impersonate them in an attempt to harm their reputation.
The United Arab Emirates is following the events in Sudan with "great concern", its foreign ministry said in a statement late Wednesday.
The ministry emphasised the "importance of resuming talks among various Sudanese forces".
"The UAE hopes that wisdom, voice of reason and constructive dialogue would prevail between all Sudanese parties, in a way that guarantees security and stability of Sudan, helps spare its people the scourge of evil, safeguard its gains and ensure its unity," the ministry said.
The UAE is Sudan's top export partner.
The United Nations has announced plans to move some of its staff out of Sudan, on the heels of the deadly crackdown on protesters in the capital Khartoum.
"We are temporarily relocating non-programme-critical UN staff, while all UN operations continue in Sudan," said UN spokesperson Eri Kaneko, as reported by AFP.
A Sudanese doctors' committee close to the demonstrators said on Wednesday afternoon that its estimated death toll over the past three days of violence had risen to more than 100, Reuters reported.
The new toll, which is still expected to rise, comes after more than 40 bodies were recovered from the Nile in Khartoum - with eyewitnesses reporting that security forces dumped bodies into the river.
Video obtained and verified by Middle East Eye shows crowds recovering a body from the Blue Nile on Tuesday amid reports of security forces dumping victims in the river.
By comparing landmarks in the video with map imagery we've been able to locate the exact spot near the Blue Nile Bridge in Khartoum where the body was pulled out of the water, just a few hundred metres away from the military headquarters and protest camp where Monday's crackdown took place.
Crowds of people were gathering on the riverbank and taking to boats to search for bodies, MEE's correspondent said.
A Sudanese alliance of protesters and opposition groups has rejected the ruling military council's invitation to talks.
"We do not accept the Transitional Military Council's invitation... because it is not a source of trust... It is imposing fear on citizens in the streets," Madani Abbas Madani, a leader of the Declaration of Freedom and Change Forces, told Reuters on Wednesday.
Sudan's ruling Transitional Military Council said on Wednesday it had launched an investigation into the recent violence in the country.
"The council has initiated an independent investigation... an urgent and transparent investigation with fast results," said the council's deputy chairman, General Mohamed Hamdan Dagalo, commonly known as Hemeti.
"Any person who crossed boundaries has to be punished."
As Middle East Eye wrote last week, since the protests began in December, Hemeti has put forward two images of himself - the champion of the protesters and the person to keep them in check - sometimes simultaneously.
The deputy head of the Sudan People's Liberation Movement-North rebel group has been detained, a spokesman for the movement said on Wednesday.
Yasir Arman had been living in exile and was sentenced to death in absentia over his actions in the group, but had returned to Sudan recently, the Reuters news agency reported.
He was arrested by security forces, the spokesman said.
Sixty people have been killed in a two-day crackdown on Sudanese protesters carried out by troops and paramilitaries, a doctors' committee close to the demonstrators said on Wednesday.
A previous toll given by the Central Committee of Sudanese Doctors had counted 40 dead since the security forces bloodily dispersed a weeks-long sit-in outside army headquarters in Khartoum on Monday.
The head of Sudan's Transitional Military Council (TMC) said on Wednesday that the council was still open to talks with opposition groups without any conditions.
Lieutenant General Abdel Fattah al-Burhan made the comment in a message to mark the Muslim Eid al-Fitr, one day after he announced that the TMC was cancelling all agreements with a coalition of protesters and opposition groups and instead was going to national elections within nine months.
