An al Qaeda-linked terrorist group claimed responsibility for the assault at Splendid Hotel—a popular meeting place for Western diplomats in the capital, Ouagadougou. (2)The attack began on Friday night and dragged on under the cover of darkness. Security forces entered the hotel early Saturday and freed 126 hostages, half of whom were hospitalized, according to Burkina Faso’s foreign minister, Alpha Barry. Of the 29 people who died, 22 have been identified, Ouagadougou prosecutor (控方律师) Maziza Sereme said. President Roch Marc Christian Kabore told the nation more than 50 people were wounded. The injured included two Burkinabe police officers, one soldier and one service member from France. It was unclear whether the death toll included the three attackers that Kabore said were killed.
