The coronavirus pandemic and the resulting closed borders have slowed but not stopped the flow of migrants. The IOM said about 138,000 people made the journey in 2019 but just 37,500 in 2020.
It is not immediately clear what countries the migrants in this latest journey were from, but many make the voyage from Ethiopia and Somalia.
In October, at least eight migrants drowned after smugglers forced them off a boat near Djibouti.
In 2017, up to 50 migrants from Somalia and Ethiopia were “deliberately drowned” when a smuggler forced them into the sea off Yemen’s coast. And in 2018, at least 30 migrants and refugees died when a boat capsized off Yemen, with survivors reporting gunfire.
