Terror attacks in Western Europe are up, but **t close to the 1970s
Extremist attacks like the blasts in Brussels on Tuesday that left at least 34 dead and 270 injured are increasing in Western Europe, but they're still **t nearly as common as they were from the mid 1970s to the mid-1990s.
Anti-government groups such as the Irish Republican Army in **rthern Ireland, Basque separatists in Spain, and Anni di Piombo in Italy helped turn such attacks into more than a daily occurrence*between 1970 and 1996.
