Protest leaders in Sudan have called for a new campaign of civil disobedience after some of them were detained by security forces.

They have ruled out negotiations with the military rulers until those responsible for killing more than 100 demonstrators last week are held to account.

Several opposition leaders were arrested soon after the meeting with Ethiopia's Prime Minister Abiy Ahmed, who was mediating with the Transitional Military Council.

Al Jazeera's Natasha Ghoneim reports.
