Sudan opposition group calls for mass protests on Tuesday

The umbrella group behind months of opposition protests in Sudan has called on "the masses" to take to the streets across the country on Tuesday.

The Sudanese Professionals' Association asked people to protest after Eid prayers and to pray for those killed in today's violent crackdown on the Khartoum sit-in.

"We also call for continuing the peaceful gatherings and organised marches everywhere after prayers," the group said on Twitter. 

The SPA also asked demonstrators to close major roads and bridges in order to "to bring public life to a complete halt".
