On Saturday Kenya's military spokesman named four men who are alleged to have been involved in the attack, which killed at least 67 people.
Closed-circuit television footage from the Westgate mall was broadcast on Kenyan television channels, apparently showing at least four alleged attackers with guns walking around the mall's supermarket and a storage room.
"I confirm these were the terrorists, they all died in the raid," Major Emmanuel Chirchir, spokesman for the Kenya Defence Forces, told Reuters.
He gave their names as Abu Baara al-Sudani, Omar Nabhan, Khattab al-Kene and Umayr.
Previously, the country stated that between 10 and 15 militants were involved in the mall attack.
Kenya's President Uhuru Kenyatta vowed not to bow to the al-Shabab group that claimed the Westgate mall bloodbath and threatened more attacks if Kenya failed to pull its troops out of Somalia. – Reuters.
