https://www.bbc.com/news/world-africa-56347756Questions have been raised over the health of Tanzanian President John Magufuli who has not been seen in public for 11 days.
Opposition leader Tundu Lissu has told the BBC that according to his sources the president is being treated in hospital for coronavirus in Kenya.
The BBC has not been able to verify this report independently.
Mr Magufuli has faced criticism for his handling of Covid-19, with his government refusing to buy vaccines.
The East African nation has not published its coronavirus cases since May.
Its 61-year-old president has called for prayers and herbal-infused steam therapy to counter the virus.
Earlier this month, at a funeral for a top presidential aide, Mr Magufuli said Tanzania had defeated Covid-19 last year and would win again this year.
The aide died hours after the vice-president of the country's semi-autonomous islands of Zanzibar, who was being treated for Covid-19.
