The death of the 28-year-old is the latest of the 90 people who have been killed since protests following the coup in October.

Protesters have remained undeterred despite the heavy crackdown by security forces.

On Thursday, thousands of demonstrators marching towards the presidential palace in the capital, Khartoum, were met by gunfire and tear gas.

Several people were carried away bleeding, the Reuters news agency reports.

The protesters want the military to hand power over to a civilian government.
