Police on the Japanese island of Okinawa have arrested a U.S. Navy seaman accused of raping a Japanese tourist as she slept at her hotel. Past allegations of sexual assault have been at the center of protests over the presence of U.S. troops and planned construction of a new U.S. military base in Okinawa. Earlier this month, the Japanese government agreed to halt construction on the new base and resume talks with local authorities who oppose it.
