The United Nations has accused Libyan guards shooting at refugees and migrants while trying to flee from air strikes.
A report from the UN Office for Coordination of Humanitarian Affairs (OCHA) said there were two air strikes late on Tuesday, one hitting an unoccupied garage, other hitting a hangar containing around 120 refugees and migrants.
“There are reports that following the first impact, some refugees and migrants were fired upon by guards as they tried to escape,’’ the OCHA report said.
However, bodies were still being recovered from the rubble, the report said, suggesting the death toll could rise.
There are still about 500 people at the detention centre at Tajoura, east of Tripoli, with four Nigerians set for release to the Nigerian embassy on Thursday.
The 53 dead was the highest publicly reported toll from an air strike or shelling since eastern forces under Khalifa Haftar launched a ground and aerial offensive three months ago to take Tripoli.
Tripoli, the base of Libya’s internationally recognised government, is in the northwest of the country.
“The number of civilian casualties caused by the conflict has almost doubled as the result of this single attack,’’ the OCHA report said, a day after UN officials said the air strikes may have constituted a war crime.
UN has repeatedly said Libya is not a safe place for rescued migrants to be sent back to and has called for refugees and migrants to be released and given safe shelter.
It has declined to directly criticise Italy for shutting its doors but said European states must help to resolve the conflict in Libya in order to stop people taking perilous sea journeys.
The centre is close to a military base and an air strike on nearby Libyan government forces on May 7 injured two people in the centre.
In spite of the risks, Libyan authorities had continued to transfer migrants and refugees into the centre, according to the U.N. report.
On May 12, 108 refugees and migrants picked up at sea by the Libyan Coast Guard were disembarked and transferred to the Tajoura detention centre, the report added.
