Haiti: At 01:00 local time, anonymous armed men invaded the president’s home in Port-au-Prince, according to Claude Joseph (05:00 GMT).
Martine Mose, the First Lady, was also hurt in the incident.
“All efforts have been made to ensure the state’s continuity,” Mr Joseph said.
He has now assumed leadership of the poor Caribbean country and encouraged everyone to keep calm.
Jovenel Mose, 53, had been in authority since February 2017, following after his predecessor Michel Martelly.
Mr. Mose’s tenure as president was marked by charges of fraud and waves of frequently violent anti-government rallies.
Earlier this year, there were large rallies in the capitol and other cities calling for his resignation.
Mr. Mose’s five-year term should have expired on February 7, 2021, five years after Mr. Martelly stepped down, according to Haiti’s opponents.
However, elections were postponed for a year, and Mr Mose maintained he had one more year to serve because he did not enter power until February 2017.
Mr Mose said in February that an effort to assassinate him and overturn the government had been averted on the day the opponents intended him to quit office.
Haiti is one of the poorest countries in the Americas due to chronic volatility, dictatorships, and natural catastrophes.
In a country where nearly 60% of the population lives in poverty, there has been an increase in vicious gang violence and robberies, as well as a decline in standard of living.
In 2010, an earthquake destroyed over 200,000 people and severely damaged infrastructures and the commerce.
A UN peacekeeping force was deployed in 2004 to assist with the country’s stabilisation, and it was only withdrawn in 2017.
