The U.N. released an urgent call for action after a shipwreck off the coast of Libya claimed an estimated 130 lives last week. It was the largest tragedy in the Central Mediterranean since the start of the year; 2021 has seen at least twice as many deaths along the dangerous migration route as the same period last year. The U.N. is calling on nations to strengthen search and rescue operations in the Mediterranean, to stop returning refugees to dangerous countries, and to allow for safe disembarkation procedures.
