Reports in Paris, the French capital, suggest Ivory Coast’s Prime Minister, Patrick Achi, is in hospital.
Reuters news agency quoted sources close to Prime Minister as saying he is having medical tests.
Mr Achi was appointed prime minister in March following the death of his predecessor Hamed Bakayoko, who had been receiving treatment for cancer in Germany.
Mr Bakayoko, himself, was appointed following the sudden death of his predecessor Amadou Gon Coulibaly last year.
Reuters says that Mr Achi went to France last week for health reasons but then returned to Ivory Coast to take part in talks about electricity problems. He then flew back to Paris on Tuesday.
The Ivorian government has not commented.
