GENEVA: Hundreds of people are feared dead or missing after attempting to cross the Mediterranean Sea, with reports of multiple shipwrecks ​in the last ten days following bad weather, the UN migration agency said on Monday.

“The final toll may be significantly higher, a stark reminder that this route remains the deadliest migration corridor in the world,” the IOM stated.

Three people — including twin girls about one year old — were confirmed ‌dead in ‌Lampedusa, Italy, after a search-and-rescue ‌operation ⁠for ​a boat ‌that left Sfax, Tunisia, the International Organization for Migration said in a statement. They died of hypothermia, according to their Guinean mother, a survivor. A man also died from the same cause, the IOM added.

Survivors from the same boat said another vessel departed simultaneously but ⁠never arrived and its fate remains unknown, the IOM said.

Over the ‌past 10 days — amid a ‍violent Mediterranean storm triggered ‍by Cyclone Harry — several boats are believed to ‍have gone missing, leaving hundreds unaccounted for, according to the IOM. Search efforts have been hampered by poor weather.
