Boutros Boutros-Ghali, the former secretary general of the UN, has died aged 93.
His death was confirmed by Rafael Dario Ramirez Carreno, the president of the UN Security Council.
As an Egyptian, Mr Boutros-Ghali was the first Arab to hold the UN's top position.
He took office in 1992 at a time of increasing influence for the world body following its decisive role in the Gulf War, serving one five-year term.
The 15-member Security Council observed a minute's silence.
