KHARTOUM - Thousands of demonstrators called Sudanese President Omar al-Bashir a "killer" on Saturday, the sixth day of protests sparked by fuel price hikes in a nation already burdened by economic pain and war.
They said the "martyr" Salah Mudathir, 28, was shot dead during a protest the day before.
Police did not release names but said four civilians were gunned down by unknown shooters during demonstrations after Friday prayers in the capital Khartoum.
"Bashir, you are a killer," a witness said about 2,000 marchers - men, women and youths - shouted after Mudathir's burial.
"Freedom! Freedom!" he said they shouted, calling for the end of Bashir's regime, which calls itself Islamist.
The latest demonstration occurred after thousands of mourners walked through the streets of the wealthy Mansheeya neighbourhood escorting an ambulance carrying Mudathir's body, the witness said.
Mudathir, a pharmacologist, belonged to a family that is prominent in business and politics.
"He was killed by a bullet to the heart this evening" while he demonstrated, a cousin told AFP on Friday night, as women wept at the family's large home.
Police said Friday's protests in the capital had been mostly peaceful following weekly Muslim prayers but that some protesters blocked roads and created "disturbance."
"Police ended the demonstrations using tear gas in a limited way," a statement said.
But "unknown shooters fired on demonstrations in Khartoum Bahri, Khartoum and Omdurman" during the protests, added the statement, carried by the official SUNA news agency.
"As a result of that, four civilians were killed."
