LONDON -- Nationalists largely were behind the bombing of national monuments in Europe during the last decade.
Breton nationalists who damaged France's Versailles Palace with a powerful bomb in 1978 said they wanted to 'punish' France for annexing their province, which once was an independent duchy.
They viewed the 17th Century palace as the symbol of centralized rule over provinces that had been largely autonomous, they said.
A group of neo-Nazi sympathizers in 1981 blew up a monument in France's Vosges Mountains commemorating the recovery of Alsace and Lorraine from Germany during the second World War.
In 1974, a bomb exploded amid a crowd of tourists at the Tower of London, killing one person and injuring 41.
The bomb was blamed on the Irish Republican Army, which wants British troops withdrawn from Northern Ireland and wants Ulster united with the Republic of Ireland.
The IRA also was responsible for bombs that exploded outside Scotland Yard and the Old Bailey, Britain's main criminal court, in 1973. One person was killed and 216 were injured in those explosions.
Police noted that the IRA bombs were designed more to injure people in the buildings than to cause serious structural damage.
