Facility in Tripoli overcrowded after 5,000 migrants arrested in the country in past week

At least five migrants have been shot dead at a Tripoli detention centre amid a mass escape from the overcrowded facility.

Libyan security forces have detained more than 5,000 migrants, refugees and asylum seekers mostly from sub-Saharan Africa in a crackdown over the past week, housing them in crowded, unsanitary detention centres, the United Nations refugee agency UNHCR has said.
