Around 70 migrants are presumed dead after going missing off the Libyan coast since late February, the International Organization for Migration said on Thursday.
The United Nations agency said 22 migrants had been found dead after boats capsized on February 27 and March 12, with 47 still missing.
In the latter tragedy, a boat reportedly carrying 25 migrants capsized off the Libyan port city of Tobruk, bringing the total number of migrants reported dead or missing in the central Mediterranean to 215 so far this year, it said.
“I am appalled by the continuing loss of life in the Central Mediterranean and the lack of action to tackle this ongoing tragedy,” said Federico Soda, IOM’s Libya chief.
He called for “concrete action to reduce loss of life, through dedicated and proactive search and rescue and a safe disembarkation mechanism.
“Each missing migrant report represents a grieving family searching for answers about their loved ones,” he added.
Libya has long been a springboard for migrants, often from countries ravaged by war and poverty, to make desperate bids to reach a better life in Europe.
Many end up drowning in the attempt, making the central Mediterranean route the world’s deadliest migration corridor.
More than 123,000 migrants landed in Italy from Libya and neighbouring Tunisia in 2021, up from around 95,000 the previous year, according to the UN’s refugee agency UNHCR.
Nearly 2,000 migrants went missing or drowned last year in the Mediterranean, compared to 1,401 in 2020, it says.
