Sudanese police fired tear gas Tuesday at hundreds of teachers in Khartoum protesting the death of a colleague in detention as demonstrators pressed on with rallies against President Omar al-Bashir's rule. Groups of doctors, students and lawyers also staged demonstrations in the capital and other areas of the country - part of protests sparked by a government decision to triple the price of bread which have rocked Sudan since December 19.

The unrest quickly escalated into nationwide rallies against Bashir's three-decades in power, with demonstrators demanding the veteran leader step down. Officials say 30 people have died in protest-related violence since then, but Human Rights Watch says at least 51 people have been killed.
