Live: Latest on Sudan crackdown

The United States, Norway and the United Kingdom have accused Sudan's Transitional Military Council of jeopardising peace and the country's political transition, a day after a violent attack on protesters in Khartoum.

"The people of Sudan deserve an orderly transition, led by civilians, that can establish the conditions for free and fair elections, rather than have rushed elections imposed by the TMC's security forces," the countries said in a joint statement on Tuesday. 

Echoing the African Union (AU) and rights groups across the world, the three countries called for an "immediate" transfer of power to a civilian-led government.

The US, UK and Norway also raised "serious concern" over the Sudanese military council's decision to stop negotiating with opposition leaders.

The umbrella group behind months of opposition protests in Sudan made a plea to local doctors on Tuesday, calling on them to head to hospitals to help treat injured protesters. 

"We call on all of our country's honourable doctors to head to the hospitals and serve in the emergency rooms to treat the wounded," the Sudanese Professionals Association said on Twitter. 

Referring to Sudan's Transitional Military Council as "the council of oppression and brutality", the group accused military forces of continuing to suppress protesters and violently targeting civilians.

US Congressman Eliot Engel, the chairman of the House Committee on Foreign Affairs, called on Donald Trump to sanction "any individuals in Sudan who have been complicit in human rights abuses against protesters".

"This is a watershed moment in the history of Sudan, and we cannot stand by as pro-democracy activists are slaughtered by the remnants of a brutal dictatorship," Engel said in a statement.

He said Sudan's military leaders must immediately end the violence against protesters and commit to establishing a civilian-led government.

Engel also called on Trump to "immediately appoint" a special envoy to Sudan. 

Here's Middle East Eye's latest wrap of the day's events in Sudan, focusing on calls by the opposition on Arab states to end their support for the military council, and for an international investigation into Monday's deaths.

The United Nations Security Council, which is currently chaired by Kuwait, will discuss the situation in the country in a closed session on Tuesday.

AFP reported that Rapid Support Forces units were firing live ammunition to disperse protesters who had erected barricades on Tuesday in Khartoum's twin city of Omdurman, citing local witnesses that it spoke to by phone.

"We gathered in our square as we usually do every year but the Rapid Support Forces and the police fired teargas and soundbombs at us and after the prayers the youth closed the main street by putting up barricades," a resident of the Bahri area told AFP.

Reuters has published photos showing small numbers of protesters manning barricades of bricks and burning tyres on the streets of Khartoum. Some flashed victory signs as their photographs were being taken. Other images showed roads barricaded with rubble, old water tanks and other detritus.

A Sudanese opposition group has called on "some Arab countries" to stop supporting the military council in a message seemingly aimed at Saudi Arabia, the United Arab Emirates and Egypt.

"We ask that some Arab countries lift their hands from Sudan and stop supporting the Military Council and consolidating the pillars of its rule with the aim of preserving it and protecting their own interests that are harmful to the Sudanese state and its citizens," said the Democratic Alliance of Lawyers, which is part of the Sudanese Professionals' Association, according to Reuters.

The UAE and Saudi Arabia pledged $3 billion in financial and material support to Sudan in late April.

Transitional Military Council Head Abdel Fattah al-Burhan and his deputy Mohamed Hamdan Dagalo have ties to the two Gulf states through the participation of Sudanese troops in the Saudi-led coalition in Yemen's civil war. Burhan visited the UAE and Egypt last month and Dagalo, visited Saudi Arabia in May.

Sudanese protests have evolved in the space of less than six months from complaints about bread prices to calls for long-term leader Omar al-Bashir to go and demands for a civilian-led transition to democracy.

Here's a summary of the key moments so far since the protests began. 

19 December 2018: People take to the streets in the city of Atbara to protest against a government decision to triple the price of bread, torching a local ruling party office. By the next day protesters on the streets of Khartoum and other cities calling for "freedom, peace, justice". Police try to disperse the crowds, resulting in at least eight deaths. Dozens more will be killed in the weeks of protest that follow

22 February 2019: Sudanese President Omar al-Bashir declares a nationwide state of emergency. He swears in a new prime minister two days later, as riot police confront hundreds of protesters calling for him to resign

6 April: Thousands gather outside the army's headquarters in Khartoum, chanting "one army, one people" in a plea for the military's support. They defy attempts by state security forces to dislodge them and troops intervene to protect them

11 April: Military authorities announce they have removed Bashir and that a transitional military council will govern for two years. Despite celebrations at Bashir's demise, protest leaders denounce the move as a "coup" and the protesters remain camped outside army headquarters.

14 April: Protest leaders call on the military council to transfer power to a civilian government

20 April: Sudan's military rulers hold a first round of talks with protest leaders

27 April: The two sides agree to establish a joint civilian-military ruling council, but talks stall over differences in the composition of the council, with both sides demanding a a majority

15 May: With negotiators reported to be close to agreeing a three-year transition to civilian rule, military leaders suspend talks and insist protesters remove barricades outside the army's headquarters. Talks resume on 19 May but break down again on 20 May, with the opposition insistent that a civilian must head the transitional governing body

28 May: Thousands of workers begin a two-day strike to pressure the military rulers and call for civilian government

3 June: At least 35 people killed and hundreds injured, according to opposition-aligned doctors, as security forces firing live ammunition move to disperse the protest camp outside army headquarters

4 June: General Abdel Fattah al-Burhan, the head of the military council, announces that all previous agreements with protest leaders are scrapped and says elections will be held in nine months

Madani Abbas Madani, a leader of the Declaration of Freedom and Change Forces opposition alliance, said a civil disobedience campaign would continue to try to force the council from power.

The opposition rejected all that Burhan said in his statement, Madani said.

"What happened, killing protesters, wounding and humiliation, was a systematic and planned matter to impose repression on the Sudanese people," he said.

Footage being shared on social media appears to show a continuing heavy presence of armed security forces on the streets of Khartoum, with members of the Rapid Security Forces (RSF) prominent among them. RSF units are reported to be stopping vehicles and searching and detaining some individuals, as this video posted on Twitter suggests.

A senior protest leader told the UK's Sky News that the country was on the verge of descending into civil war, with some army officers ready to march on Khartoum to support the civilians.

Sudan's opposition Congress Party also posted images of Eid prayers and funeral prayers at Al-Sahaba mosque in the Burri Imtidad Nasser of Khartoum.
