U.N. Secretary-General Antonio Guterres says Robert Mugabe’s “role in securing the independence of Zimbabwe and the fight against apartheid are key parts of his legacy.”

According to U.N. spokesman Stephane Dujarric, the secretary-general will be sending a letter “offering condolences to the government and people of Zimbabwe” following Mugabe’s death earlier Friday.

Dujarric also noted Mugabe’s “notable contributions” when chairing organizations such as the former Organization of African Unity and the Southern African Development Community.

He also said Mugabe was a regular participant in meetings and conferences at U.N. headquarters in New York.

Dujarric said “the United Nations remains strongly committed to supporting Zimbabwe in its efforts to promote inclusive stability, sustainable development, democratic governance and human rights.”

Meanwhile current and former leaders of Ghana have lauded Zimbabwe ex-president Robert Mugabe following his death in Singapore.

Ghanaian president Nana Akufo-Addo tweeted in Saturday that “Robert Mugabe will be remembered, above all, for his immense contribution to the liberation of Zimbabwe and Southern Africa from imperialism, colonialism and racist rule. His dedication to the cause of Pan-Africanism is fully acknowledged.”

Former Ghanaian President Jerry John Rawlings also tweeted that Africa lost “a bold and noble statesman.”

Rawlings said Mugabe “lived for the dignity of your fellow Black. Your African pride, and dignity and audacity were unassailable.”

Former President John Dramani Mahama wrote on Facebook of being saddened by “the passing of a legend of the African liberation struggle.”

Mahama said of Mugabe “Despite his flaws in later years, he will always be remembered as a great fighter for freedom and a dedicated Pan Africanist.”

Meanwhile Zimbabwe’s president has declared former President Robert Mugabe a national hero, the country’s highest posthumous honor.

President Emmerson Mnangagwa said the African country would observe an official mourning period until Mugabe is buried; he didn’t say when the funeral would take place.

Mnangagwa announced on Friday that Mugabe died in Singapore at age 95. He didn’t say when the body would return to Zimbabwe.

He thanked Singapore for “unmatched hospitality and medical care they extended to our leader up to the very end”

Mnangagwa was a long-time loyalist until Mugabe fired him from his Cabinet in 2017. He called Mugabe “a great teacher and mentor” and a “remarkable statesman of our century.”
