Japanese police are investigating a suspected guerrilla attack on the US Army after two small explosions occurred outside a military base south of Tokyo, police said today.

An American soldier who vanished from his Army unit in 1965 today pleaded guilty to deserting the military and fleeing to North Korea to avoid dangerous duty on the Korean peninsula and Vietnam.

Saluting and standing at attention, accused American army deserter Charles Jenkins surrendered to US military authorities at a base near Tokyo, today, to face charges that he left his unit in 1965 and defected to North Korea.
