Planted by unknown perpetrators, a bomb exploded at LaGuardia Airport in New York City, killing 11 people and seriously injuring 74 others.

On December 29, 1975, a bomb detonated near TWA baggage reclaim terminal at LaGuardia Airport in New York City. The blast killed 11 people and seriously injured 74 others. To date, the crime remains unsolved. Investigators theorized it might have been committed by anti-Yugoslavia Croatians or agents of the Yugoslavian government itself, intending to discredit the opposition. The attack occurred during a four-year period of heightened terrorism within the United States: 1975 was especially volatile, with bombings in New York City and Washington, D.C., and two assassination attempts on President Gerald Ford.
