“When the centres are overflowing, migrants are taken out, there is no money to feed them all,” Ibrahim says. “Some guards are good people, but some of them are corrupt.”He hints at the tangled relationship which exists between centre personnel, smugglers, militia and human traffickers, which pass desperate migrants between themselves like a resaleable human commodity.The guards at detention centres may take money from the traffickers, then hand the migrants over.Or smugglers tip off the coastguard when their migrants are due to sail to Europe so that they will be captured and passed to militias.Or militias will seize migrants in the streets on the grounds that they do not carry the necessary documentation, a requirement in Libya. “They pretend to arrest illegal migrants and then keep them in their centres without food and water, take their money, exploit them, abuse women,” Ibrahim says.
