Security forces have fired tear gas on Sudan protesters causing casualties, according to an AFP report citing eyewitness accounts.
Mobile phone lines inside Sudan were cut ahead of the latest round of anti-military protests planned on Wednesday in the capital Khartoum, according to a Reuters witness.
Mobile internet connections in Sudan have been suspended since a military takeover on Oct. 25, despite a judge issuing several orders to restore them.
No to military rule" and "the people choose civilian rule", demonstrators chanted, as well as slogans against Sudan's ruler, top general Abdel Fattah al-Burhan.
During protests on November 14, six people were killed and the chief of Qatari network Al Jazeera's bureau in Khartoum was arrested before being released two days later.
The renewed protests came as US Secretary of State Antony Blinken urged Africans to watch out for rising threats to democracy as he began a three-nation tour of the continent in Kenya.
"We have seen over the last decade or so what some call a democratic recession," Blinken said in Nairobi.
Blinken told Sudan's military the country stood to regain badly-needed international aid if it restores the "legitimacy" of civilian government.
"It's vital that the transition regain the legitimacy that it had," he said.
