GENEVA — At least 73 migrants are missing and “presumed dead” after their boat sank off the Libyan coast, according to the International Organization for Migration (IOM).

Only seven survivors made it back to the shore following Tuesday’s shipwreck, the IOM said. So far 11 bodies have been recovered.

Libya has become a launching point for those trying to reach Europe, and more than 130 people have already died this year making the dangerous journey.
