The United Nations Security Council has imposed sanctions on six people it accuses of involvement in the trafficking and smuggling of Libyan migrants, after a video appearing to show African migrants being sold as slaves sparked global outrage last year.

The sanctions against four Libyans — including the head of a regional Coast Guard unit — and two Eritreans are believed to represent the first time that traffickers have been put on an international sanctions list, the BBC says.

The Netherlands, backed by France, Germany, Britain and the United States, asked the 15-member council’s Libya sanctions committee last month to impose a global asset freeze and travel ban on the six people, Fitiwi Abdelrazak, Ahmad Oumar al-Dabbashi, Ermias Ghermay, Mohammed Kachlaf, Abd al-Rahman al-Milad and Mus’ab Abu Qarin.

In May, Russia asked for more information on the proposed action, putting a hold on the sanctions. But Russia then backed down, and the council imposed sanctions on Thursday.
