Migrants’ mass graves are not uncommon in Libya. Last year, authorities unearthed the bodies of at least 65 migrants in the Shuayrif region, 350 kilometers (220 miles) south of the capital, Tripoli.

The first mass grave with 19 bodies was found on Friday in a farm in the southeastern city of Kufra, the security directorate said in a statement, adding that authorities took them for autopsy.
