ROME: Bodies washing ashore day after day. Phone calls from relatives going unanswered. Migrants’ tents abandoned overnight.

Migrants trying to reach Europe are vanishing in droves in what are known as “invisible shipwrecks” but governments responsible for search and rescue are withholding information about what they know.

The beginning of 2026 ranks as the deadliest start to any year for people trying to cross the Mediterranean — an unprecedented 682 confirmed missing as of March 16 — according to the United Nations’ International Organization for Migration. But the real death toll is almost certainly much higher.

Human rights groups are increasingly struggling to verify tolls as Italy, Tunisia and Malta have quietly restricted information on migrant rescues and shipwrecks along the deadliest migration route in the world. The news barely makes headlines, in part because the lack of transparency prevents journalists from confirming reports.

“It’s a strategy of silence,” said Matteo Villa, a researcher focusing on migration and data at the Italian Institute for International Political Studies think tank.
