Mariam al-Mahdi, Sudan’s opposition leader will spend at least a week in jail after refusing to pay a fine of 2,000 Sudanese pounds ($42).
This came after a Sudanese emergency court sentenced the opposition leader to a week in jail.
Police also detained several people for marching on parliament to protest a state of emergency.
It should be noted that in Sudan, institutions such as judiciary have not enjoyed full autonomy as the long serving dictator President Al Bashir extend his rule to independent intitutions.
Deputy chief of the opposition Umma Party, led by her father and former premier Sadiq al-Mahdi, she and her sister Rabah were among those arrested earlier on Sunday.
Protest organisers had called for a march to challenge the state of emergency, imposed nationwide by President Omar al-Bashir on February 22.
Bashir’s move came after a crackdown on rallies against his iron-fisted rule failed to deter demonstrators.
The president has ordered a slew of tough measures to quell the protests, including banning all unauthorised rallies and setting up the emergency courts to probe offences.
Sunday’s procession was to start at the Umma Party offices in the capital’s twin city of Omdurman.
