President Mugabe has expressed bitterness over African countries that voted in favour of a decision by western countries to invade Libya resulting in the killing of President Muammar Gaddafi.
Officially opening the 67th World Health Organisation (WHO) Regional Committee for Africa Summit in Victoria Falls Monday, President Mugabe who was the guest of honour, castigated the killing of "innocent" people by "greedy and envious" world leaders.
He also spoke at length about the killing of Iraqi leader Saddam Hussein adding that he (Mugabe) had no respect for former Britain and America leaders Tony Blair and George Bush after they connived to kill him (Hussein) on unfounded claims of Iraq having weapons of mass destruction.
"Because of envy that Iraq has huge deposits of oil underground with one man Saddam Hussein sitting on the massive wealth, they decided to attack him.
"But they said if we just go and attack him like that the world will be on us. Let's contrive something to attack him with, then they thought of saying we are destroying weapons of mass destruction, Saddam Hussein has weapons of mass destruction," said President Mugabe speaking off the cuff.
He said it was known that Hussein had no weapons of mass destruction, adding that Zimbabwe also had similar problems with the Blair government.
Mugabe said Hussein had managed to usher peace in his country after managing to unite the Suni and Shia muslim groups.
"The weakness of our world system is that when innocent countries are attacked, we fold our arms," he said.
"The man had managed to unite his country but he is killed. When they discovered that there were no weapons of mass destruction, tonnes of oil had been sucked.
"As if that lesson was not headed in Iraq, they came to Libya, to Gaddafi. Yes he may have been a dictator but he was a friend of his people, a lover of his people, one who desired that his people should develop and not live in poverty and had managed to draw water from underneath our world to create a huge massive dam for the benefit of his country which is semi desert.
"He became friends with us, he wanted to democratise the African Union to be better politically and economically united," lamented President Mugabe.
He was referring to the 2011 United Nations Security Council Resolution, which authorised the imposition of a no-fly zone on Libya in response to that country's civil war.
The UNSC had initially failed to garner the necessary two-thirds majority, but African countries were later persuaded to vote in favour of the resolution.
South Africa, Nigeria and Gabon were among the non-permanent members who voted in support of the resolution.
President Mugabe said Africa sought the support of Russia and China.
"Yes, the matter came to the UNSC. The whites said he must be attacked and China and Russia said no. The matter could not have proceeded any further because of the necessary two-thirds majority, with Russia and China abstaining.
"Then it came to us the poor Africans. The poor Africans, sometimes not thinking well about the consequences of those attacks. So, what did we have? Quite disgraceful and shameful thing," added the Africa's longest serving President.
He said African countries, including Zimbabwe, pleaded with China and Russia to exercise their veto, but the two said the best they could do was to abstain in light of the three African members and the Arab contingent's support of NATO.
President Mugabe, who is a former African Union chair, lamented lack of humanitarianism among some leaders who he said kill their own people for having different religious and political views.
He appealed to WHO's new director-general Dr Tedros Adhanom Ghebreyesus, who is Ethiopian, to represent Africa with African values.
"It's the pride that Africa has and we know he will not let us down but will try to make Africa meet giant steps in health because we are dying possibly the most.
"Mothers and children are dying because of us leaders sometimes, because of our ambition, because of certain concepts we have, maybe religious and because of selfishness, we have the drive to kill.
"I am a Catholic and Catholicism is not different form the other religions Methodist, Anglican, the beliefs are the same, commandments are the same. Where is that humanitarianism that we were taught in our religion to love one another?"
He said Africans should live in harmony and show love to each other.
He said he was worried that Nigeria, a great nation with grand status, failed to trace the 200 school children abducted by Boko Haram insurgents.
