In Mozambique on Tuesday, 14 “deeply traumatized” male migrants were rescued from a sealed shipping container on a lorry bound for South Africa. According to the International Organization for Migration (IOM), 64 other men on the truck, died from asphyxiation.

In an interview with UN News’s Daniel Johnson, IOM’s Sandra Black explains where the migrants came from and what the agency is doing to raise awareness about the dangers of such journeys.
