Sudanese security forces have attacked a pro-democracy protest outside the military headquarters in the capital, Khartoum. Live ammunition has been used and eyewitnesses say there are fatalities.
Sudan has been governed by a Transitional Military Council since President Omar al-Bashir was overthrown in a coup in April.
Protesters have been demanding that a civilian government should take over the running of the country. The security services moved on the main protest site early today.
Khartoum residents reported hearing heavy gunfire and seeing smoke rising from the area around the army headquarters.
At least five people are reported to have been killed and a number injured.
