RED_POPE: I could also add to the list the first case of politic terrorism - emperor Alexander the Third who was blown up by a bomb three weeks before he was about to grant a Constitution to the Russian Empire (middle of 19th century). But that would not be the well-known fact.

Cheers, mate!

PS Just to be precise Tchernobyl is in Ukraine, and has been duly claimed by some Ukranian girl in the same thread :)
