A bomb explodes on board Cyprus Airways Flight 284 while flying over the Mediterranean Sea, killing 66.

Cyprus Airways Flight 284 was a de Havilland Comet that exploded during a flight to Nicosia International Airport on 12 October 1967 after a bomb was detonated in the cabin. The airliner crashed in the Mediterranean Sea and all 66 passengers and crew members on board were killed.

The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, on the south by North Africa, and on the west almost by the Morocco–Spain border. The Mediterranean Sea covers an area of about 2,500,000 km² (970,000 sq mi), representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only 14 km (9 mi) wide.

October 12 is the 285th day of the year in the Gregorian calendar; 80 days remain until the end of the year.
