Rescued migrants must not be sent back to Libya: UN

Italy's far-right Interior Minister Matteo Salvini has told prosecutors investigating his treatment of migrants that "you only give me more power"

Migrants and asylum-seekers rescued while trying to cross the Mediterranean to Europe should not be sent back to Libya, where they risk "serious abuses," the UN's human rights agency has warned.

In an update to its official position on returns to Libya, the UNHCR warned against any such move, mooted recently by Italy's Interior Minister Matteo Salvini in a standoff with other EU nations on the migrant influx.

"Insecurity and the lack of governance have enabled illicit activities such as corruption as well as people-smuggling and human trafficking to thrive, further fuelling instability in the country," the agency wrote this month.

Proposals to set up processing centres for asylum applications in Libya and other North African countries, as called for in a deal struck by EU leaders in June, did not change its position, the UN's refugee body said.

The UNHCR said this week that nearly 1,600 people have died trying to reach Europe by sea since the beginning of this year.

It estimates that 679,000 migrants were registered living in Libya as at June 2018, though the actual number could be closer to a million.

Those rescued by Libyan coastguard vessels are held in detention centres indefinitely, which currently contain some 8,000 people, the agency said.

"In all facilities, detention conditions reportedly fail to meet international standards," with migrants at "very high risk of torture and other forms of ill-treatment, including rape and other forms of sexual violence, forced labour as well as extortion."
