CAIRO — Military forces arrested Sudan’s acting prime minister and senior government officials Monday, disrupted internet access and blocked bridges in the capital Khartoum, the country’s information ministry said, describing the actions as a coup.

In response, thousands flooded the streets of Khartoum and its twin city of Omdurman to protest the apparent military takeover. Footage shared online appeared to show protesters blocking streets and setting fire to tires as security forces used tear gas to disperse them.

Protesters could be heard chanting, “The people are stronger, stronger” and “Retreat is not an option!” as plumes of smoke from burning tires filled the air.
