ROME – Migrants seeking a better life in Europe have died by the thousands in the Mediterranean Sea in recent years while fleeing poverty and bloodshed in Africa, the Middle East and Asia.
The precise figure of deaths is unknown. But the ill-documented toll is rising again Sunday as rescuers search for an estimated 700 passengers from a capsized boat north of Libya. The Italian Coast Guard has confirmed 24 deaths and 28 people rescued, but authorities expect the death toll to rise.
Authorities count only those bodies found in the sea, on shore, or aboard boats where migrants can die of thirst or exposure. Survivors often tell of fellow passengers who lost their lives at sea, but the bodies are never found.
Here is a list of the deadliest migrant boat events, based on bodies recovered or survivor accounts:
