At least 20 people have died and others have been taken hostage when Islamist gunmen stormed a hotel in the capital city of Burkina Faso, a hospital director says.
Security forces began an assault to reclaim the Splendid Hotel in the early hours of Saturday and entered its lobby, part of which was on fire, a witness said. The hotel is frequented by Westerners, which may have made it a target for the militants.
About 30 hostages including the labour minister were freed from the hotel, said Minister of Communications Remis Dandjinou. No one has said publicly how many hostages might be in the hotel.
It was the first time militants have carried out an assault in the capital of Burkina Faso and comes as a setback to efforts by African governments, France and the United States to prevent attacks that have destabilised the region.
It follows a raid on a luxury hotel in Mali last November in which two attackers killed 20 people, including citizens of Russia, China and the United States. There have been many attacks by militants in other countries in West Africa in recent years and the vast majority of those killed have been Africans.
Robert Sangare, director of Ouagadougou's university hospital centre, said that among an initial batch of 15 people brought to hospital some had bullet wounds while others had injuries from falls.
Patients saw around 20 bodies, and one European woman being treated at the hospital said the attackers appeared to target Westerners, said Sangare, who had spoken to the patients.
The hotel is sometimes used by French troops with Operation Barkhane, a force based in Chad and set up to combat Islamist militants across West Africa's vast, arid Sahel region.
A US defence official said France, the former colonial power, had requested US intelligence surveillance and reconnaissance support in the city, and at least one US military member in Burkina Faso was giving "advice and assistance" to French forces at the hotel.
The government has not ruled out calling for help from French special forces stationed in the country, Burkina Faso Foreign Minister Alpha Barry told Reuters.
France normally has up to 200 special forces troops in the country.
