(CNN) Sudan's pro-democracy movement has called for "civil disobedience" throughout the country beginning Sunday, days after a bloody military crackdown killed more than 100 people in the capital Khartoum.

The Sudanese Professionals Association (SPA), a body that led protests against former leader Omar al-Bashir, said the civil disobedience campaign will only end when the ruling generals "transfer power to a civil transitional authority in accordance with the Declaration of Freedom and Change (DFC)."

It added, in a statement released Saturday, that the campaign meant not going to work and "general civil disobedience for a civil state."

According to Agence France-Presse, Sudanese police fired tear gas at protesters gathering tires, tree trunks and rocks in a bid to build a roadblock.

Two people were killed Sunday, according to the Central Committee of Sudan Doctors (CCSD), bringing the death toll to 118 people since the June 3 massacre -- which saw dozens killed and hundreds more injured when soldiers and paramilitary groups opened fire on a sit-in that has been ongoing since the dramatic fall of Bashir in April.
