Tanzania's president John Magufuli, who had previously dismissed the severity of Covid-19, has died aged 61.
Vice President Samia Suluhu Hassan confirmed his death on Wednesday after the president vanished from the public eye for more than two weeks leading to increased speculation over his health, including suggestions he had contracted coronavirus himself.
Hassan said Mugufuli died from the heart disease that had plagued him for a decade.
Burial arrangements are under way while the nation will undergo 14 days of mourning and flags will be flown at half mast. State television broadcast mournful and religious songs.
Magufuli had not been seen in public since February 27 however officials denied on March 12 that he had fallen ill.
He was Tanzania's first president to die while in office.
“Dear Tanzanians, it is sad to announce that today 17 March 2021 around 6pm we lost our brave leader, President John Magufuli who died from heart disease at Mzena hospital in Dar es Salaam where he was getting treatment," the vice president said on state broadcaster TBC.
Prime Minister Kassim Majaliwa said on Friday that he had spoken to Magufuli, and blamed the narrative of the president's ailment on some "hateful" Tanzanians living abroad.
Tundu Lissu, Magufuli's main rival in the October election when the president won a second five-year term, had suggested Tanzania's leader had been flown to Kenya for treatment for COVID-19 and then moved to India in a coma.
Leader to be remembered for 'contribution to Tanzania's development'
After the death was announced, opposition leader Zitto Kabwe said he had spoken to Vice President Hassan to offer condolences for Magufuli's death.
"The nation will remember him for his contribution to the development of our country," Kabwe said in a statement published on Twitter.
According to Tanzania's Constitution, Vice President Hassan, 61, should assume the presidency for the remainder of the five-year term that Magufuli began serving last year after winning a second term. She would be the East African nation's first female president.
Born in the semi-autonomous archipelago of Zanzibar, Hassan studied economics in Britain, worked for the UN's World Food Programme and then held various government posts before becoming Tanzania's first female vice president in 2015.
Hassan said Magufuli was admitted on March 6 to Jakaya Kikwete Cardiac Institute for heart problems and discharged the next day. A week later he felt bad and was rushed to Mzena hospital where he was getting treatment under supervision of doctors from the cardiac institute.
Magufuli had dismissed Covid's severity
Magufuli frustrated the World Health Organization (WHO) during the pandemic by playing down the threat from Covid-19, saying God and remedies such as steam inhalation would protect Tanzanians.
The former chemistry teacher had mocked coronavirus tests, denounced vaccines as part of a Western conspiracy to take Africa's wealth, and opposed mask-wearing and social distancing.
Tanzania stopped reporting coronavirus data in May last year when it had reported 509 cases and 21 deaths, according to the WHO, which has urged the government to be more transparent.
After mounting pressure, he eventually admitted in February the nation had a coronavirus problem.
He was re-elected for a second term in 2020, winning 84 per cent of the vote in an election the opposition said was marred by irregularities and whose results it rejected.
