Italy's populist premier Giuseppe Conte on Wednesday deplored the overnight air raid on the Tajoura migrant detention centre in Tripoli, which killed at least 44 people and severely injured over 130.
"We deplore the shocking and tragic attack on a detention centre in Tripoli," Conte tweeted in English.
Italy's has repeatedly called for a truce in the three-month-old battle for control of the city between forces loyal to Libya's rival governments.
"We’ve repeatedly called for a cessation of hostilities and we reaffirm that the only solution in Libya is a political solution," the tweet added.
The internationally recognised government in Tripoli blamed eastern warlord Khalifa Haftar's forces for the attack on the migrant shelter in Tajoura suburb located next to a military camp.
Haftar's self-styled Libyan National Army has in turn blamed the attack on shelling by militias loyal to the United nations backed government.
