(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.

Goldstone Report was critical of Israel and Hamas in Gaza fighting
@highlight
It focused more on allegations of Israeli war crimes
@highlight
Its author now says he would come up with different findings
@highlight
Israeli should have been more cooperative, he writes in Washington Post op-ed piece
The fact that @placeholder backtracked must lead to the shelving of this report once and for all."
