Sudan's paramilitary Rapid Support Forces (RSF) said on Saturday that the Sudanese army had surrounded one of its bases in south Khartoum and opened fire with heavy weapons, as gunfire could be heard in several parts of Khartoum and adjoining cities.
A Reuters witness saw cannon and armored vehicles deployed in streets, and heard the sound of heavy weaponry in the vicinity of the headquarters of both the army and the RSF.
However, the Sudanese army spokesperson Brigadier General Nabil Abdallah told AFP that soldiers of the RSF attacked its bases in Khartoum and elsewhere, adding that the clashes are ongoing and the army is "carrying out its duty to safeguard the country."
Al Jazeera also reported that the air traffic has stopped at the Khartoum International Airport following the clashes.
The Chinese embassy in Sudan issued a security notice, reminding Chinese citizens and institutions in the country to stay on high alert and step up security precautions.
