All U.S. service members in Okinawa have been restricted to their bases and residences and banned from drinking alcohol in response to a fatal traffic accident in the prefectural capital over the weekend, U.S. Forces in Japan announced Monday.

"The new restrictions follow an accident Sunday morning in Naha. . . . Alcohol may have been a factor," USFJ said.

The announcement follows the arrest of a marine who was reportedly involved in an accident that resulted in the death of a Japanese man in Naha.
