Libya considers releasing all migrants 'for their own safety' following Tripoli attack
The strike left at least 130 wounded when it hit a hangar in which the migrants were detained in the Tripoli suburb of Tajoura.
Fathi Bashagha, the interior minister of Libya's Government of National Accord (GNA) told the assistant to the UN special envoy to Libya, Maria do Valle Ribeiro, his government was accountable for the safety of Libyan civilians, including detained migrants.
However, Bashagha said the authority did not have the capacity to protect the centres in the face of airstrikes from advanced F16 jets, according to ministry.
Ribeiro also discussed the Tanjoura attack with Mohammed Al-Shibani, Libya's deputy interior minister for migration affairs, agreeing on the need to transfer the hundreds of survivors to safer accommodation.
The Libyan justice ministry condemned the attack, vowing to work with humanitarian and migration organisations to repatriate the migrants or resettle them in third countries, because Libya's compromised security situation could not provide them the safety they require.
Despite this, it was revealed on Thursday that around 300 migrants of the centre's original 600 detainees were still being held there.
The International Organisation for Migration (IOM) said it was providing humanitarian assistance to the remaining detainees.
The IOM was unable to confirm reports that dozens of migrants had fled on Tuesday night after the raid.
The UN's humanitarian office OCHA, quoting survivors, said guards at the centre fired on migrants trying to flee causing no casualties, but the GNA interior ministry denied this as "rumours and false information".
The IOM said its teams had "located" and transferred to hospital "a group of injured migrants who left Tajoura after the attack in the surrounding neighbourhood".
"Innocent lives were lost in the attack on Tuesday night, and immediate action is needed from all sides," the IOM's Libya chief of mission, Othman Belbeisi.
The GNA and its arch-foe, militia leader Khalifa Haftar traded blame for the deadly assault.
But despite a storm of outrage, a divided UN Security Council failed to unanimously condemn the attack in an emergency meeting Wednesday after the US did not endorse a proposed statement.
Migrants from Algeria, Morocco, Sudan, Somalia and Mauritania as well as other African nations were among the victims, Amin al-Hachmi, a spokesperson for the GNA health ministry said.
The majority of migrants at the centre in Tajoura, a suburb east of the capital Tripoli, were from Eritrea and Sudan.

Two of the five hangars that made up the centre were hit by the air strike, while "hangar number 3", which housed more than 120 migrants, took a direct hit.
According to the IOM, of the more than 600 migrants detained in Tajoura, 187 were registered with its "Humanitarian Voluntary Return" programme, which helps migrants go back to their home countries.
"The IOM continues to call for an end to the arbitrary detention and reminds all parties that civilians are not a target," it said in a statement.
Some 3,300 migrants are still detained in and around the Libyan capital in centres "considered at-risk" in light of the fighting between the opposing forces of Hafter and the GNA, the IOM added.

Rights groups say migrants face horrifying abuses in Libya, which remains prey to a multitude of militias vying for control of the oil-rich country.
Their situation has worsened since Haftar - supported by the UAE, Egypt and Saudi Arabia - launched on 4 April an offensive to conquer Tripoli, where the Turkey-backed GNA is based.
UN agencies and humanitarian organisations repeat regularly their opposition to the return of migrants arrested at sea to Libya, where they find themselves in "arbitrary detention" or at the mercy of militias.
