Libya authorities uncovered nearly 50 bodies this week from two mass graves in the country’s southeastern desert in the latest tragedy involving people seeking to reach Europe through the chaos-stricken North African country. Officials said one grave was found Friday in a farm in the southeastern city of Kufra and at least 19 bodies were unearthed. Another mass grave was found after raiding a human trafficking center in the city. The grave had at least 30 bodies with survivors saying there were nearly 70 buried there, authorities said Sunday.
