Security forces raided the offices of Sudan's opposition group, the Sudanese Professionals‘ Association (SPA), the group said late on Saturday, forcing them to nix a press conference ahead of major protests.
The SPA and the military have clashed repeatedly in recent weeks, disagreeing over the timeline for a transition to democracy after the protest movement ousted former strongman President Omar al-Bashir. Since talks between the two groups broke down earlier this month, a violent crackdown has killed at least 128 people across the country, according to protest organizers.
Demonstrators have repeatedly accused the military of trying to make a power grab in Bashir's absence.
"This represents a violation of liberties that is even worse than the regime of the former president," SPA spokesman Ahmed al-Rabie told Reuters news agency after the raid on their offices.
"This is a bad sign for the atmosphere of mediation between the two parties."
