Jewish historian Reuven Moskovitz, who was awarded a prestigious peace prize, fired a broadside at Israel during his acceptance speech.
The outspoken award winner used the glittering occasion to launch an attack on Israel's policies which have caused misery for millions of Palestinians.
And he called on Europe to exert pressure on Ariel Sharon to stop the persecution of Palestinians.
"All Israel's governing politicians have transformed the lives of the Palestinian people into an intolerable hell with their sanctions and expulsions," he said at Monday’s award ceremony.
Germany's Aachen Peace Prize was also won by Palestinian-born activist Nabila Espanioly, but it was Moskovitz who stole the show.
Moskovitz, 75, said the acts of violence by young Palestinians and fanatics could not be justified, but he said they were often a result of hopelessness and indignation.
Originally from Jerusalem, Moskovitz called on Europe to put pressure on Israeli Prime Minister Ariel Sharon.
