Bazooka Fired at U.N. as Cuban Speaks
Launched in Queens, Missile Explodes in East River
By Homer Bigart
United Nations Headquarters was fired upon yesterday with a 3.5-inch bazooka from across the East River. The attack coincided with a demonstration by anti-Communist Cubans at the front entrance against the presence of Maj. Ernesto Che Guevara of Cuba.
A single shell from the bazooka, a portable rocket launcher used by the Army, arced across the river from Queens and feel harmlessly about 200 yards from the shore. The blast sent up a geyser of water and rattled windows in the headquarters just as Major Guevara, Havana's Minister of Industry, was denouncing the United States.
Shortly before, a hysterical woman brandishing a hunting knife with a seven-inch blade detached herself from 50 anti-Guevara pickets and tried to force her way into the front entrance. The police subdued the leather-jacketed woman, and later quoted her as saying she intended to assassinate Major Guevara.
In the sealed-off General Assembly Hall, the blast was clearly heard over the voice of Major Guevara, who was assailing United States foreign policy and rejecting a denuclearization pact for the Western Hemisphere.
He paused not a moment in his speech. Later, strolling through the delegates' lounge in his green fatigue uniform and highly polished black boots, he said, with a languid wave of his cigar, that the explosion "has given the whole thing more flavor."
But the police saw no humor in the incident. Had the rocket shell crashed against the glass-and-concrete facade of the headquarters building, there would almost certainly have been casualties. The rocket launcher was found abandoned directly opposite the United Nations in a weed-strewn lot on the east bank of the East River. The device consisted of a tube about three feet long which was bound by ropes to a crate filled with ballast. It had a sighting device, which, according to the police, was fixed on the misty silhouette of the 38-story United Nations Headquarters.
It was fired, apparently by a clock-like device, at 12:10 P.M. At that time a noisy demonstration in front of the United Nations Headquarters was at a peak of tension. The crowd of Cuban exiles was hurtling curses at the police, who, at the time were carrying away Molly Gonzales, the woman who said she wanted to cut down Major Guevara with a hunting knife.
