The decision was taken by the civilian-military sovereign council at a meeting in Niyala, the capital of South Darfur state, a statement by the ruling body said. "The sovereign council, in a meeting with the government of South Darfur, ordered the closure of the border with Libya and Central African Republic as it threatened the security and economy of the country," the statement said.
In recent years, media reports have claimed that many rebels from Sudan's war-torn region of Darfur had crossed into Libya to build up their military capabilities, with some joining Libyan strongman Khalifa Haftar's forces.
Darfur fell into widespread conflict in 2003 when ethnic minority rebels took up arms against the Arab-dominated government of Bashir, who was toppled in April this year.
