HAVANA, July 20, 1964 (UPI)Raul Castro, Minister of the Armed Forces, charged today: that United States marine; guards at the Guantanamo Bay naval base shot and killed a Cuban sentry at dusk yesterday.
As a result of the charge, diplomatic circles speculated that Premier Fidel Castro might withdraw the peace overtures he made to the United States in a recent interview.
Although the Cubans have alleged two other shootings of sentries along the Guantanamo Bay fence in the last six weeks, this was the first time that anyone had been reported killed. Two sentries were reported wounded in the earlier incidents.
The Defense Ministry, in a communique signed by the Premier's younger brother, said the marine post at 7:07 P.M. fired six shots at the Cuban sentry box. It said Pvt. Ramon Lopez Pena, 19 years old, was shot twice in the neck and died 20 minutes later. No further details were given.
