Sudanese authorities said on Sunday that 58 police personnel had been injured during protests the previous day against military rule, and that tear gas had been used only to confront attacks on security facilities and vehicles, state TV and Reuters reported.
The Khartoum security committee's statement added that 114 people had been arrested and faced prosecution after Saturday's protests, the latest in a series of rallies against an October 25 coup that upended a transition towards democratic elections.
Medics aligned with the protest movement said earlier that violence by security forces had caused 178 injuries among demonstrators, including eight with live bullet wounds.
At least 48 people have been killed in crackdowns on protests against the coup, the medics say.
Internet and phone communications were disrupted on Saturday, and security forces fired tear gas as they blocked protesters from reaching the presidential palace.
A deal announced by the military in November to reinstate Prime Minister Abdalla Hamdok has failed to stem the protests, which are calling for the military to withdraw from politics altogether.
