Sudanese Prime Minister Abdullah Hamduk said today, Wednesday, that "the blood of the martyrs will not be wasted," stressing that justice will be done for those killed in the protests that led to the overthrow of the former President Omar al-Bashir.

Calls for retribution for those who died in Sudan’s celebrations have increased for a year since the start of their uprising.

"Those who faced bullets with bare breasts and made this possible, their blood will not be wasted," Hamaddock told hundreds. "We have formed legal committees, and we have amended laws for justice."

Close to the presidential palace in the center of Khartoum, hundreds of young men and women demonstrated, carrying the country's flags and pictures of those who fell during the protests, chanting "Blood for blood is what we accept blood money" and raised banners saying "Retribution for the martyrs".

At least 177 people were killed by the crackdown on the movement, according to Amnesty International, including more than a hundred during the break-up of the June sit-in in Khartoum. However, the Doctors ’Committee, close to the demonstrators, estimated the death toll at more than 250.

Army and riot police blocked the roads leading to the presidential palace.

The demonstrations began in December in protest against the doubling of the news price, and lasted for months, during which the army toppled Bashir, who had ruled Sudan for 30 years.
