The Diciotti rescued the migrants from a trafficker's boat on Aug. 16. The ship has been docked in Sicily for days, and Italy's government is refusing to let it disembark passengers unless other EU nations pledge to take them, AP reported.

UN High Commissioner for Refugees Filippo Grandi urged European countries in a statement Saturday "to do the right thing and offer places of asylum for people rescued from the Mediterranean Sea in their time of need."

Grandi said from Geneva that it's time to end "a race to the bottom on who can take the least responsibility for people rescued at sea."
