Recent violence by militias in North Darfur prompted authorities to declare a state of emergency on July 13.

The Sudanese Professionals’ Association, which has spearheaded protests since December, said security forces arrested Yassin Abdel-Karim.

Sudanese activists said on Monday that at least 11 people were killed in clashes with security forces during mass demonstrations demanding a transition to civilian rule.

At least 128 people have died in the country since June 3, when the military violently dispersed a sit-in camp in Khartoum.

Sudan's strongman president is gone, but civilians worry he'll be replaced by the brutal militiamen who once followed his orders in Darfur.

Witnesses told media the forces attacked medical clinics and looted hospitals and committed multiple sexual assaults.

Footage shared on social media and verified by Reuters showed chaotic scenes of people fleeing through streets as sustained bursts of gunfire crackled in the air. People rushed to carry away those who had been hit.

Violence flared in Sudan's capital Khartoum late on Monday after the military council and opposition groups said they had agreed to a power structure for the country's transition following the ouster of President Omar al-Bashir last month.
