At least 70 people are missing after a boat carrying migrants sank off the coast of Libya in the Mediterranean Sea. The vessel, which departed from Libya’s Tajoura port on April 3 for Europe, capsized early on April 4 within Libyan waters. A commercial ship rescued 32 survivors, including citizens of Pakistan, Bangladesh, and Egypt, and transported them to Italy’s Lampedusa island. Two bodies were also recovered during the operation.

According to the International Organization for Migration (IOM) and the UN Refugee Agency (UNHCR), the boat carried over 100 passengers, including a child. Survivors reported rough seas and high waves that caused the boat to take on water before overturning. The German group Sea-Watch said it spotted the distressed vessel from the air and saw several people floating near the wreck.

UNHCR spokesperson Filippo Ungaro said the boat was unfit for such a journey, and further investigation is needed to confirm the number of missing. IOM estimates up to 120 people may have been aboard, making it one of the deadliest recent migrant shipwrecks in the region.
