The Simon Wiesenthal Center said Thursday it passed the names of four suspected former Nazi criminals to German authorities so that they can be brought to justice before they die. A statement from the Jerusalem office of the center did not identify any of the four, but said they were accused of crimes including "murder in concentration camps or taking part in shootings." The names were the first results of Operation Last Chance, a drive launched this year by the center to track down former Nazis for World War II-era crimes before they die of old age. The center, which is offering â‚¬10,000 for information which leads to a suspect being charged, said two of the four were identified following tips from relatives. It said a third was tracked down from a tip from a member of their former military unit. It gave no details about the fourth.
