U.N. investigates reports of migrant mass graves in Libya

GENEVA (Reuters) - U.N. investigators are seeking to verify reports of mass graves thought to contain the corpses of migrants at a trafficking hub in Libya, they said in a report on Monday that also documented incidents of rape, murder and torture.

Libya is a major transit point for Africans seeking to make the perilous journey to Europe across the Mediterranean but many instead find themselves enslaved by militias and traffickers or forced into prostitution.
