Questions persist 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 transported to Kenya for treatment in hospital against COVID-19. The BBC has not been able to verify this report independently.

Mr Magufuli has faced criticism for his coping with COVID-19 sanitary crisis, 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, President Magufuli said Tanzania had defeated COVID-19 last year and would win again this year.

Mr Lissu says he was told that President Magufuli had been flown to Kenya for treatment at Nairobi Hospital on Monday night.

According to the opposition leader, the president has suffered a cardiac arrest and is in a critical condition.

There has been no official response from the government, which has warned against publishing unverified information about the Tanzanian leader, who was last seen at an official event in Dar es Salaam on 27 February.
