Malek Merset, a spokesman with the Tripoli-based health ministry, told The Associated Press that the airstrike took place in the capital's Hadaba area, just south of the city centre where fighting has been raging for months.
Tripoli has been the scene of fighting since April between the self-styled Libyan National Army led by Gen. Khalifa Hifter and an array of militias loosely allied with the weak but U.N.-supported government that holds the capital. Footage shared online Saturday showed wounded people with bandages and blood on their legs being treated in a hospital.
Hifter launched a surprise military offensive April aimed at capturing Tripoli despite commitments to attend a national conference weeks later aimed at forming a united government and moving toward elections.
