The announcement raised expectations the statement Thursday could address nearly four months of anti-government protests demanding that longtime President Omar al-Bashir step down and could be a sign that he is relinquishing power.

Organizers of the protests urged masses to converge and join an ongoing sit-in that has been underway in the capital, Khartoum, since the weekend.

Sudanese radio is playing military marches ahead of the announcement.

The TV s says there'll be an "important statement from the armed forces after a while, wait for it."

It comes after clashes between Sudanese security forces and protesters, after an attempt to break the sit-in, leaving 22 dead since Saturday.
