Via Israel Today:
Declassified CIA documents have revealed that Yasser Arafat's “Black September” terrorist organization tried to assassinate then Israeli prime minister Golda Meir in New York City in 1973.
According to the documents, which were reported on by Israel National News, Black September operatives planted three cars loaded with explosives along the route Meir's motorcade took through the city. However, the bombs failed to explode due to a technical malfunction.
The CIA reportedly saw the incident as a major breach of its security protocols and therefore covered up the incident while it re-examined its security array.
