The pope's minister for peace and justice was accused yesterday of speaking like a Holocaust denier after comparing Gaza to a "big concentration camp".

Cardinal Renato Martino, a veteran Vatican diplomat with years of experience as the Pope's delegate to the United Nations, told an interviewer for L'Avvenire, the daily paper of the Italian bishops, that "nobody" in the Israel-Hamas dispute "sees the interests of the other, but only their own". He continued: "But the consequences of egoism are hatred for the other, poverty and injustice. The ones who pay are always the defenceless populations. Look at the conditions in Gaza: more and more it resembles a big concentration camp."

He added that "both sides" were to blame for the dispute and must be separated like feuding brothers. "The world cannot just look on, doing nothing," said Cardinal Martino. His comments were later echoed by Pope Benedict XVI, who said "the military option is not a solution and violence from whichever side must be firmly condemned".
