Former United Nations Secretary-General Boutros Boutros-Ghali died Thursday afternoon at the age of 93 in a Cairo hospital, according to Egypt's Middle East News Agency.

The grandson of an Egyptian prime minister, Boutros-Ghali served as Egypt's minister of state for foreign affairs and then deputy foreign minister before he was elected to lead the United Nations in 1992.

His term as secretary-general was contentious – with criticism over his handling of the Rwanda Genocide and the collapse of Yugoslavia. He is the only secretary-general to not be re-elected to a second term, after the United States threatened to veto his re-election at the Security Council.

After leaving the U.N., Boutros-Ghali led the La Francophonie organization of French-speaking countries, before heading an Egyptian human rights council under former President Hosni Mubarak, a position he held until 2012.

Egyptian press reported that Boutros-Ghali had been admitted to the hospital Tuesday after breaking his pelvis.

His death was confirmed by the U.N. Security Council, which observed a minute of silence in honor of the former secretary-general, according to the BBC .
