Lieutenant General Abu Bakr Mustafa will replace Salah Abdallah Mohamed Saleh, known as Salah Gosh, as chief of Sudan's National Intelligence and Security Service (NISS), Shams El Din Kabbashi Shinto said.
Shinto also announced the sacking of Sudan's ambassadors to Washington and Geneva and said all army and police officers who participated in street protests which led to the ousting of former President Omar al-Bashir last week would be released.
* Sudan's main protest group on April 14 called for the immediate handover of power to a civilian transitional government and said it would maintain street demonstrations to push for its aims.
Such a transitional council should be protected by the Sudanese armed forces, the Sudanese Professionals Association said in a statement.
"The Sudanese Professionals Association affirms the continuation of the sit-in and the exercise of all forms of peaceful pressure to achieve the objectives of the revolution," it said.
