Israeli Intelligence Minister Eli Cohen has led a delegation to Khartoum, a spokesman said Tuesday, months after Sudan and the Jewish state struck a deal to normalise ties.

A tense calm fell Tuesday on Sudan's Darfur region after days of inter-ethnic violence claimed at least 155 lives, left scores wounded and displaced tens of thousands, a tribal leader and a regional official said.

More than 80 people have been killed in two days of ongoing clashes in Sudan's restive Darfur, doctors said Sunday, just over two weeks since a long-running peacekeeping mission ended operations.

Sudan's hybrid United Nations-African Union mission in Darfur is set to end its 13-year peacekeeping operations in the conflict marred region Thursday, even as recent violent clashes leave residents fearful.

"The joint United Nations-African Union mission in the Darfur region of Sudan (UNAMID) will officially end operations on Thursday, when the Government of Sudan will take over responsibility for the protection of civilians in the area," the mission said in a statement on Wednesday. 

US lawmakers were set Monday to back legislation granting Sudan legal immunity for past attacks, a final step in a historic deal removing Khartoum from Washington's blacklist of state sponsors of terrorism.

Secretary of State Mike Pompeo on Monday hailed what he called a "fundamental change" in the relationship with Sudan after it officially left the US terror blacklist.

The United States on Monday formally removed Sudan's state sponsor of terrorism designation, 27 years after putting the country on its blacklist, the US embassy in Khartoum announced. 

Sudan needs $150 million in aid to cope with the flood of Ethiopian refugees crossing its border from conflict-stricken Tigray, the UN refugee agency chief said Saturday during a visit to a camp.

Sudan's former prime minister and top opposition figure Sadiq al-Mahdi died from a coronavirus infection on Thursday, his party said.

Sudan's government on Tuesday denied having information about the visit of an Israeli delegation to Khartoum announced the day before by an official from Tel Aviv.
