US soldiers killed in helicopter collision

Two US Army helicopters have crashed at a base in Washington, killing four soldiers.

An earlier report from Joint Base Lewis-McChord indicated two other soldiers were injured.

However, spokesman JC Mathews said the two OH-58 Kiowa helicopters that crashed last night were both two-seat aircraft.

They crashed in the south-west training area of the base near Tacoma.

None of the victims has yet been identified.
