The gunmen in the Mali hotel siege sorted hostages by their faith, according to Kassim Traore, a Malian journalist who was in a building about 50 meters from the siege.
The New York Times writes that Traore "said the attackers had told hostages to recite a declaration of Muslim faith as a way separating Muslims from non-Muslims. Those who could recite the declaration, the Shahada, were allowed to leave the hotel."
As the New York Times points out, The Shabab, a Qaeda affiliate in East Africa, used a similar vetting process to differentiate Muslims from non-Muslims in the attack at the Westgate Mall in Nairobi in 2013.
U.S. troops were not involved in the raid on the Radisson Blu in Bamako that ended the siege, a U.S. defense official has told ABC News.
Sky News has pictures from inside the Radisson Blu in Bamako, Mali where the hostages have now been freed. So far 27 people have been reported killed.
Hostages are leaving the Radisson Blu hotel right now, the BBC's Faisal Irshaid has just tweeted.
