The U.S. Marine Corps said Friday it will ban Okinawa-based marines from consuming alcohol around the time of the July 21-23 Group of Eight summit.

The announcement of the ban, which will be effective from July 20 to 24 both inside and outside U.S. military bases, follows Monday's arrest of a marine on suspicion of trespassing in a private home and molesting a 14-year-old girl living there.

The marines will also be required to be in uniform at all times during the five-day period, the U.S. Marine Corps in Okinawa said.

Lt. Gen. Earl Hailston, the chief of U.S. Marine Corps forces in Okinawa, said he is certain each marine understands the need for the disciplinary measure as well as the importance of the Okinawa summit.
