The fiery speech by Abbas to a special session of the UN-backed Human Rights Council in Geneva threatened to stir up new tensions with Israel, just as US-led efforts to calm the situation in the region are getting under way.
Abbas criticised Netanyahu for comments a week earlier suggesting that a World War II-era Palestinian religious leader had persuaded the Nazis to carry out a policy that exterminated 6 million Jews.
Abbas said Netanyahu's allegations manipulate the sentiments of Jews about "the most horrendous crime known in modern history committed by the Nazis."
"He prefers to blame Palestinians for everything even the Holocaust. You all know that this is totally false. It is untrue and baseless," he said.
"When the Israeli prime minister tries to absolve Adolf Hitler from his ugly crimes, against the Jews, and blame Palestinians for these crimes, he is trying thereby to justify the crimes committed against the Palestinian people," he said, according to an official translation of his remarks, which were delivered in Arabic.
Netanyahu has said the violence is the result of incitement by Palestinian leaders, including Abbas, as well as social media. The Palestinians say it is the result of frustration stemming from nearly 50 years of Israeli occupation, repeated failed peace efforts and a lack of hope in gaining independence anytime soon.
Abbas said the human rights situation in the Palestinian territories is at its "worst and most critical since 1948" the year of Israel's independence and insisted "it is no longer useful to waste time in negotiations for the sake of negotiations. What is required is the end of the occupation in accordance with international legitimacy.
