The smugglers are reported to have fired on passengers as they tried “to extort more money” from the migrants. Survivors reported gunfire as the boat capsized.

“Survivors of the incident have reported to U.N. and partner staff that an over-crowded boat packed with at least 152 Somalis and Ethiopians departed 23 January from the Al Buraiqa coast in Aden in a boat headed across the Gulf of Aden towards Djibouti,” IOM said in a statement. “The boat capsized amid reports of gunfire being used against the passengers.”

The IOM says Yemen’s conflict has subjected refugees and migrants to risk of human rights violations, including arbitrary arrest and trafficking.
