The UN Security Council will hold an emergency meeting on Wednesday to discuss an air strike on a detention center in Libya that killed scores of migrants, diplomats said.
The meeting requested by Peru, which holds the council presidency, will be held behind closed doors from 3:00 pm (1900 GMT).
Council members will hear a briefing from representatives of the UN refugee agency and the UN political affairs department.
At least 44 people were killed when the strike hit the Tajoura detention center east of Tripoli late Tuesday and more than 130 were severely injured, the UN said.
No-one has so far claimed responsibility for the attack.
Tajoura held at least 600 refugees and migrants, including women and children. UN agencies said they expected the death toll from the attack to rise.
UN envoy Ghassan Salame has called for an independent investigation and warned that the attack may constitute a war crime.
