Sudan’s Prime Minister Abdalla Hamdok has resigned amid political deadlock and widespread protests following a military coup that derailed the country’s fragile transition to democracy.

Hamdok’s decision, announced in a televised address late on Sunday, comes six weeks after he returned to his post in a deal with the coup leaders he argued could save Sudan’s political transition.

But the pro-democracy movement rejected that agreement, and Hamdok failed to name a new government as thousands of people continued to protest against the military’s power grab.

In his resignation speech, Hamdok said a roundtable discussion is needed to agree on a new "national charter” and to "draw a roadmap” to complete Sudan’s transition to democracy.

"I decided to give back the responsibility and announce my resignation as prime minister, and give a chance to another man or woman of this noble country to … help it pass through what’s left of the transitional period to a civilian democratic country,” Hamdok said.

The announcement throws Sudan’s political future even deeper into uncertainty, three years after an uprising that led to the overthrow of long-time leader Omar al-Bashir.

An economist and former United Nations official widely respected by the international community, Hamdok became prime minister under a power-sharing agreement that promised multi-party elections in 2023.

But the military-civilian ties became frayed by the army’s refusal to cede power, and on October 25, Hamdok was removed and placed under house arrest by the military. He was reinstated on November 21 in a deal that called for an independent technocratic cabinet under military oversight. But the pro-democracy movement denounced that agreement, insisting that power be handed over to a fully civilian government.

‘Dangerous turning point’

Hamdok said on Sunday that his efforts to bridge the widening gap and settle disputes among the political forces have failed.

He also warned that the ongoing political stalemate since the military takeover could become a full-blown crisis and damage the country’s already battered economy.

"I tried as much as I possibly could to prevent our country from sliding into a disaster. Now, our nation is going through a dangerous turning point that could threaten its survival unless it is urgently rectified,” he said.

The prime minister’s resignation came hours after Sudanese security forces violently dispersed the pro-democracy protesters against the coup, killing at least three people, according to the Central Committee of Sudanese Doctors (CCSD).

The medical group, which is part of the pro-democracy movement, said one of the dead was hit "violently” in his head while taking part in a protest march in the Sudanese capital, Khartoum. A second person was shot in the chest in Khartoum’s twin city of Omdurman, the CCSD said, adding that dozens of protesters were also wounded.

The protests came despite tightened security and blocked bridges and roads in Khartoum and Omdurman. Internet connections were also disrupted ahead of the protests, according to advocacy group NetBlocs. Authorities have used such tactics repeatedly since the October coup.

Sunday’s deaths have brought the death toll among protesters since the military takeover to at least 57, according to CCSD. Hundreds have also been wounded.

Following Hamdok’s resignation on Sunday, the United States urged Sudan’s leaders to "set aside differences, find consensus, and ensure continued civilian rule”.

In a statement on Twitter, the US Department of State also called for the appointment of the next prime minister and Cabinet to "in line with the (2019) constitutional declaration to meet the people’s goals of freedom, peace, and justice”.

But Cameron Hudson, a non-resident senior fellow at the US-based think tank, the Atlantic Council, said Sudan’s next prime minister will most likely be under the influence of the military.

"What we’ve seen in the last two months since the coup in Sudan is virtually the re-establishment of the Bashir regime without Omar al-Bashir. We’ve seen the military undo the vast majority of the reforms, we’ve seen the economic progress halted and financial assistance from the international community suspended. We’ve seen the intelligence services re-empowered to arrest and detain people,” he told Al Jazeera.

"We’ve seen nearly 60 people killed, and more than that raped, injured and arrested and tortured throughout the course of these protests over the last month. So we have seen a wholesale re-establishment of the previous regime in the military’s effort to control the political outcome in the country.

"What we are likely to see is the military try to appoint a new prime minister, who will likely be compliant with the military and under the military’s influence.”
