Thousands of people have rallied on the Japanese island of Okinawa in protest of plans to relocate a U.S. military base. Local officials signed on to a deal last week that will move the base from a densely populated urban area to a more remote location. But a movement of Okinawa residents has opposed the base altogether and pushed for ousting U.S. forces off the island, citing environmental concerns and sexual assaults by U.S. soldiers on local residents. On Friday, thousands of people surrounded a government building and staged a sit-in inside.
