As demonstrations began yesterday on mobilization day, Sudanese security forces took to the streets of Khartoum.
This day of mobilization is a test for the anti-army front, which began a confrontation with the authorities in early July, the day after the bloodiest day of the confrontation, when nine protesters were killed on June 30.
This was followed by sit-ins, which the front promised would be unlimited.
Gatherings resumed during the Eid al-Adha holiday last week as activists hope to regain momentum for their movement.
At the forefront of their slogans is Blue Nile State, where tribal conflict has killed 33 people and injured 108 since the start of the week, according to the Ministry of Health.
Eyewitnesses said military forces were deployed to the Roseira area, which was the epicenter of the violence on Saturday.
Opponents of the coup see the key to solving the problem in the hands of the generals and their former rebel allies, who accuse Khartoum of whipping up ethnic and tribal tensions for personal gain.
