Japanese boy hurt by falling US helicopter window

Japanese officials have said a boy has been injured in Okinawa after a metal window frame fell from a US military helicopter.

The incident will do little to help escalating anti-American sentiments on the southern island.

Officials of Ginowan city said the window fell on Wednesday morning from a CH-53 helicopter and landed on a school playground, leaving a boy with minor injuries from small gravels stirred up from the ground.

About 50 children were outside at the school next to the Marine Corps Air Station Futenma at the time.

Last week, a part of another US military helicopter fell on a kindergarten.

The base in a crowded residential area of Okinawa is a source of anti-US military sentiment and safety concerns.

Its planned relocation has been delayed as many residents want it entirely off of Okinawa.
