According to a doctor's organization, at least nine people were killed by live ammunition during demonstrations against the military's participation in the government in Sudan.
Hundreds of peaceful demonstrators took to the streets in the capital Khartoum on Thursday to demand democracy and were injured, some seriously, by security forces, the Sudanese Medical Committee said on Friday.
Many of them nevertheless marched towards the presidential palace on Friday to make their demands heard, it said.
Last October, the military took power in the country of 44 million people.
At the beginning of January, the civilian head of government, Abdullah Hamdok, who ruled the country together with representatives of the military, resigned.
There have been bloody street protests again and again against the continued participation of the military in government, which has been accused of serious human rights violations and corruption.
According to the medical committee, 112 demonstrators have died since January.
East African Sudan was ruled with an iron fist by Islamist President Omar al-Bashir for almost 30 years.
The long-time ruler was driven out of office in April 2019 by months of mass protests and a military coup.
As a result, the military and the civilian opposition agreed on an interim government that would pave the way for democratic elections.
Extensive economic reforms were planned, through which the military would have to accept considerable economic losses.
It was also a nuisance for the military that Hamdok pushed ahead with the investigation of human rights violations.
