The BBC is to broadcast a documentary series called "The Age of Terror", covering 40 years of terrorism. So that could include -
The Dublin bombings, 1974
The car bomb assassination of Orlando Letelier, Washington 1976
The bombing of Cubana Flight 455, 1976
The assassination of General Omar Torrijos of Panama, 1981
The sinking of the Rainbow Warrior, 1985

I'm sure that the bombing of the Moneda Palace, Santiago Chile, and the murder of Chile's elected president won't count as terrorism. The BBC would probably call that "an uncooperative relinquishing of the reins of government".
