Sudan shuts border with Libya and Central African Republic, citing security threats
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 Saudi-backed Libyan warlord 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.
Tens of thousands of people have been killed in the years-long conflict in Darfur and more than two million displaced, according to the United Nations.
The overall violence has eased in recent years in Darfur, but there are reports that African migrants regularly cross into Libya through the vast and arid region.
Sudan lies at the heart of migratory routes that connect East and West Africa to the Mediterranean and Europe.
Thousands of African nationals attempt to reach the Mediterranean through Sudan every year with a plan to ultimately reach European shores.
Sudanese paramilitaries said they captured 138 Africans last week, including dozens of Sudanese, trying to enter Libya illegally.
During Bashir's ongoing corruption trial, a witness told the court earlier this month that his army-owned firm had supplied military equipment to neighbouring countries using funds allegedly received illegally by the ousted Sudanese leader.
The witness did not specify which countries received the equipment, or whether the supplies included weapons.
But there have been allegations that Bashir's regime had supplied weapons to rebel groups in Central African Republic.
The poor and largely lawless CAR has been struggling to recover from the bloodshed that broke out when then president Francois Bozize, a Christian, was overthrown in 2013 by mainly Muslim Seleka rebels.
Earlier this year, the CAR government and 14 armed groups signed a peace agreement negotiated in Khartoum.
Bashir was ousted by the army on April 11 after months of protests against his three-decade rule.
