Burkina Faso’s government says 26 people were killed and a further 56 injured after Islamist militants attacked a hotel in the capital, Ouagadougou, popular with foreigners.
Al-Qaeda in the Islamic Maghreb (AQIM) has said it carried out the attack, which began on Friday night.
Those killed come from at least 18 different countries, and include two French nationals.
Burkina Faso is to observe 72 hours of national mourning for the victims.
The siege at the Splendid Hotel was declared over after a joint operation by local and French security forces.
At least four attackers died in the assaults. There were claims that some of those involved were women.
As well as the luxury hotel, a cafe and another hotel nearby were targeted. The operation to take back the hotel lasted through the night and into the morning.
