A high-level delegation from the from the Libyan government in the east paid a visit on Monday to the southern city of Sabha after the Libyan National Army (LNA) seized control of it earlier this month.
The interior, health and junior justice ministers of the eastern government, which is based in Benghazi, were seen meeting local officials in the municipality of Sabha in pictures sent to Reuters by members of the visiting delegation.
The officials later visited the main hospital and a court, journalists said.
The LNA, led by Khalifa Haftar, had launched a campaign this month in southwestern Libya.
The LNA has secured Sabha airport and other strategic sites in the area in recent days, after local groups handed them over without a fight.
The LNA’s campaign is aimed at combating militant groups and securing oil facilities in the south, which include El Sharara oilfield, Libya's biggest.
On Monday, LNA forces killed a suspected al-Qaeda fighter called Adel Ahmed al-Abdaly when they stormed his house in Sabha, LNA spokesman Ahmed Mismari said.
Otherwise the city has been largely quiet since the arrival of the LNA.
