Landmines planted by warlord Khalifa Haftar's militia have killed 39 civilians south of the Libyan capital Tripoli, according to the country's national mine action authority on Tuesday.
In a statement, the Libyan Center for Mine Clearance and War Remnants said 71 civilians were also injured by Haftar's explosives.
It, however, did not specify a date for the casualties.
The Libyan army recently inflicted heavy blows to Haftar and liberated Tripoli and Tarhuna, in addition to other strategic locations, including Al-Watiya airbase, from his militia.
The internationally recognized government has been under attack by Haftar's forces since April 2019, with more than 1,000 killed in the violence.
