Migrants arrive in Tripoli after being rescued by the Libyan coastguard on 9 January (Reuters)
Survivors from a boat that sank off Libya's coast on Tuesday said about 50 people who had embarked with them were missing and feared dead.
Libyan coastguard vessels picked up about 300 migrants from three boats off the coast of the North African country on Tuesday, but one of the boats foundered and the coastguard only found 16 survivors.
"We found the migrant boat at about 10 o'clock this morning, it had sunk and we found 16 migrants. The rest were all missing and unfortunately we didn't find any bodies or (other) survivors," said Nasr al-Qamoud, a coastguard commander.
Several of the survivors, who were brought back to a naval base in Tripoli, said there were originally about 70 people on board the boat when it set off near the town of Khoms, east of the capital. The two other migrant boats were found off Zawiya, west of Tripoli.
A Nigerian woman who had been on board the boat that sank, Zainab Abdesalam, told Reuters that the migrants had waited several hours to be rescued and that the survivors were extremely weak.
"I feel so disappointed because I could not make it to where I want to go," she said, sobbing. "I feel so disappointed and I don't want to go to prison."
Libya is the most common departure point for migrants trying to reach Europe from Africa by sea.
More than 600,000 have crossed the central Mediterranean in the past four years, generally travelling in flimsy inflatable craft provided by smugglers that often break down or puncture.
Under heavy pressure from Italy, some Libyan armed factions have blocked smuggling since last summer.
Libya's Italian-backed coastguard has also stepped up interceptions, returning migrants to Libya where they are detained and often reenter smuggling networks.
The number of people stuck in Libyan detention centres rose dramatically in 2017.
Amnesty International said last month that as many as 20,000 people are being held in detention centres and are subject to "torture, forced labour, extortion, and unlawful killings".
The International Organization for Migration (IOM) estimated that 2,800 migrants died last year trying to reach Italy from North Africa, down from 4,600 in 2016. Some 119,000 people made it alive to Italy in 2017 against 181,400 the year before.
