TARHOUNA, Libya (Reuters) - Libyan authorities have dug 12 bodies from four more unmarked graves in the city of Tarhouna, adding to the scores of corpses already discovered since the area was recaptured in June by the Government of National Accord (GNA). Tarhouna had for years been controlled by a militia known as the Kaniyat, run by the local Kani family, which fought alongside Khalifa Haftar’s eastern-based Libyan National Army (LNA). The GNA has issued arrest warrants for Kaniyat leaders who are now believed to be in eastern Libya. When Turkish support helped the internationally recognised GNA take back Tarhouna in a sudden advance in June, its fighters found a hospital piled with bodies and unmarked graves containing missing people.
