Robert Mugabe's Singapore trip 'for routine medical check-up', says information ministry

Zimbabwean President Robert Mugabe is in Singapore for medical reasons, prompting opposition figures to question whether the 93-year-old still has the stamina to run the country.

State media, quoting an information ministry statement, said the world's oldest head of state left on Friday for "a routine medical check-up" and will be back later this week.
