Sudanese forces arrested around 160 people on the border with Libya who were en-route to the war-torn neighbouring country to work as "mercenaries", a state-linked paramilitary group said Sunday.
"The joint security forces stationed at the Sudanese-Libyan border arrested 160 people who were going to work as mercenaries to fight in Libya, including two foreigners," Sudan's Rapid Support Forces (RSF) said in a statement.
The RSF is led by Mohamed Hamdan Dagalo, a leading member of Sudan's transitional ruling council.
"Sending Sudanese to fight in Libya as mercenaries is unacceptable," said General Jaddo Hamdan, the RSF's commander in North Darfur state.
"We have been monitoring and securing the border with Libya to combat illegal migration, human trafficking and all cross-border criminal enterprises," he added.
Sudan is currently undergoing a fragile democratic transition after massive protests last year prompted the military to topple long-time autocrat Omar al-Bashir.
In January, a United Nations panel of experts said many Arabs from Sudan's conflict-wracked region of Darfur and neighbouring Chad were fighting as "individual mercenaries" in Libya.
The panel said they belonged to the same tribes that made up a majority of RSF personnel, but said there was no "credible evidence" that the RSF itself had deployed in Libya.
The UN experts' report also said several Darfuri armed groups operating in Libya "have participated in various clashes and military operations alongside Libyan warring parties".
Sudan's Darfur region itself remains scarred by war after a rebellion in the early 2000s against al-Bashir was brutally suppressed.
Libya has turned into a regional proxy-war in recent years, amid chaos following the 2011 uprising that toppled and killed dictator Moamer Kadhafi.
Since 2015, a power struggle has pitted Libya's UN-recognised, Tripoli-based Government of National Accord (GNA) against forces loyal to Libyan National Army (LNA) commander Khalifa Haftar, who is based in the east of the country.
Last month, Khartoum arrested 122 people including eight children in western Darfur who were allegedly intending to serve as mercenaries in Libya's civil war.
In an interview with AFP in June, Sudan's then foreign minister Asma Abdalla denied that Sudanese forces were involved in the conflict in Libya.
