Benghazi: An airstrike hit a detention centre for migrants early on Wednesday in the Libyan capital, killing at least 40 people, a health official in the country's UN-supported government said.

The airstrike targeting the detention centre in Tripoli's Tajoura neighbourhood also wounded 80 migrants, said Malek Merset, a spokesman for the health ministry. Merset posted photos of migrants who were being taken in ambulances to hospitals. Footage circulating online and said to be from inside the migrant detention centre showed horrific images of blood and body parts mixed with rubble and migrants' belongings. The UN refugee agency in Libya condemned the airstrike on the detention centre, which houses 616 migrants and refugees.
