(CNN) -- The chairman of a U.N. mission whose report accused Israel of  "actions amounting to war crimes" during its fight against Hamas says he would have reached different conclusions if the Israeli military had been more forthcoming and if he had known the results of subsequent investigations. "If I had known then what I know now, the Goldstone Report would have been a different document," wrote Richard Goldstone, a former South African jurist, in a Washington Post op-ed column Friday. Israel, which has long been critical of the conclusions presented to the U.N. Human Rights Council on its war against Hamas forces in Gaza in 2008-09, on Saturday called for the body to cancel the findings.
