Zimbabwe's president Robert Mugabe is reported to be gravely ill in a Singapore hospital.
Local media is reporting that the 88-year-old, who is believed to be suffering from prostate cancer, is surrounded by close family members.
A Zimbabwean cabinet meeting has been postponed amid reports Mr Mugabe will hand power to defence minister Emmerson Mnangagwa.
The Zimbabwe government insists Mr Mugabe is in good health, saying he flew to Singapore to help his daughter enrol in a local university.
The ABC reports that Singapore University registration does not begin until September.
