UN Secretary General Ban Ki-moon says he sees no concrete evidence Israel and the Palestinians have carried out credible, independent probes of alleged war crimes in the Gaza Strip. "No determination can be made on the implementation of the UN resolution by the parties concerned," Ban said on Thursday in a report that contains the responses provided by Israel and the Palestinians. The UN's fact-finding mission, headed by South African judge and former international war crimes prosecutor Richard Goldstone, had accused Israel of committing war crimes during the 22-day assault on the Gaza Strip, which began on December 27, 2008. In an interview published in the December 8, 2009 edition of the newspaper al-Mashahid al-Siyasi, Musa Abu Marzouq, Hamas' second in command, said, “All paragraphs in the Goldstone report convict Israel and totally exonerate Hamas from any misconduct." Over 1,400 Palestinians were killed in the Gaza war. There was widespread international criticism of the Israeli military for its use of disproportionate force in the Gaza war, which was exemplified by the fact that most of the dead and injured were civilians.
