Kenya's military caused the collapse of three floors of the Westgate Mall in the deadly terrorist siege, a top-ranking official disclosed, while the government urged patience with the pace of an investigation that has left key questions unanswered.
Seven days after 67 people were killed in the attack on the upscale shopping center, there is still no clear word on the fate of dozens who have been reported missing and no details on the terrorists who carried it out.
The account of the roof collapse raises the possibility that the military may have caused the death of hostages in its rescue attempt. An undisclosed number of people are feared to be buried in the rubble.
The official said autopsies will be conducted on any bodies found to determine the cause of death from the militants or the structural collapse. The high-ranking government official spoke to The Associated Press yesterday on condition of anonymity because he was not authorized to divulge sensitive information.
The official also confirmed that Kenyan troops fired rocket-propelled grenades inside the mall, but would not say what caused the floors to collapse, if the action was intentional, or if it was an accident.
The account at least partially backs up information given to AP on Wednesday by another official who said RPGs fired by soldiers created a gaping hole in the mall's roof and caused the floors to collapse.
Four huge explosions had rocked the mall Monday and dark smoke poured out the likely time that the floors collapsed.
A soldier who was returning from the mall Tuesday while carrying a rocket launcher told the AP reporter that he had fired it inside. The soldier spoke on condition of anonymity because he was ordered not to talk to the media.
The government has not said publicly what caused the collapse. One official had earlier suggested it was caused by a mattress fire in the Nakumatt department store.
Presidential spokesman Manoah Esipisu said structural engineers are examining the collapse. FBI agents, along with investigators from Britain, Canada and Germany, are participating in the inquiry. Results are not expected until next week at the earliest.
Police are trying to determine if the attackers stored ammunition in the mall hours or even days before the attack, and investigators are tracing the ownership of a car that has been discovered and is believed to have been used by the gunmen.
