Khartoum: Protesters took to the streets amid the sound of gunfire on Monday, calling for the end to President Omar al-Bashir's 30-year rule.
The current wave of unrest began in December, initially over an economic crisis but quickly escalated into calls for an end to President Omar al-Bashir's 30-year rule.
Security forces have responded with a violent crackdown and dozens of people have been killed.

Elsewhere, two people including a solider were killed, hours after security forces attempted to break up a sit-in outside the military headquarters in the capital, Khartoum, activists said.
The sit-in is part of more than three months of nationwide protests against al-Bashir.
Activists said security forces, mostly from the powerful and widely-feared National Intelligence and Security Service, on pickup trucks fired tear gas, rubber bullets and live ammunition to break up the sit-in.
