"Block all streets and bridges"

Protest leaders have called for a campaign of civil disobedience around Sudan to respond to the attack on the sit-in. 

The opposition Sudanese Professionals Association called for protesters in every city to "block all streets and bridges" as a message to the ruling military council. 

"We call for a campaign of comprehensive civil disobedience to bring down the treacherous, murderous military council and complete our revolution."
