The bodies of 28 Sudanese army officers involved in a failed coup against former president Omar al-Bashir in 1990 have been found in a mass grave, prosecutors said on Thursday. 

Sudan extended a curfew in and around the capital Khartoum for 10 days from Saturday as coronavirus cases mount, state media reported. 

A year after one of Africa's longest serving leaders, Omar al-Bashir, was ousted from power in the face of mass street protests, Sudan is still reeling from daunting crises including deep economic woes. 

Sudan's economy has sunk into a deep crisis since the overthrow of longtime autocrat Omar al-Bashir almost a year ago, risking collapse and social unrest in a country in transition.

Sudanese security forces deliberately killed 241 people in a crackdown on a pro-democracy protesters in June, an international rights group said Thursday.

South Sudan's government forces and other armed groups have "deliberately starved" civilians by denying aid access and displacing communities, a United Nations rights probe said Thursday.

South Sudan's president said on Saturday he would return to a system of 10 states, a key opposition demand, paving the way for a unity government and an end to the country's civil war.

"The compromise we have just made is in the interest of peace...I expect the opposition to reciprocate," Salva Kiir said, after a meeting of top government and military officials in the capital Juba.

Sudan's justice ministry said early Thursday it had signed a deal with the families of the American servicemen killed in the 2000 bombing of the USS Cole in Yemen.

Sudan's cabinet said Thursday that the country's leader General Abdel Fattah al-Burhan had made no promise to Israel's prime minister of "normalising ties" between the two countries.

The latest round of peace talks between South Sudan's two rival leaders has failed to strike a deal on the vital issue of internal boundaries, mediators said on Friday.
