New Waco inquiry ordered
The FBI has now admitted using 'pyrotechnic devices'
The US Department of Justice has reopened an investigation into the 51-day Waco stand-off between the FBI and the Branch Davidian cult after it was revealed that agents fired potentially flammable tear gas canisters.
The leader of the cult, David Koresh, and about 80 followers, including 25 children, died.
The military-type canisters differ from civilian tear gas in that "the military canisters may have contained a substance that is designed to disperse the gas using a pyrotechnic mixture," Mr Collingwood said.
The revelations contradict congressional testimony of high-ranking Justice Department officials including that of Attorney General Janet Reno.
"It is absolutely critical that we do everything humanly possible to learn all the facts as accurately as possible and make them available to Congress and the public," she said.
She said she was "very, very frustrated" that the information had taken so long to emerge.
But she added that she still believed the FBI was not responsible for the deaths.
Officials, who requested anonymity, said two military tear gas canisters were fired hours before the fire began.
The canisters bounced off the roof of the concrete bunker and landed in an open field, according to these officials.
Independent investigators concluded the fire began simultaneously in three places.
Based on information from bugs planted on the compound, the FBI maintains that the Davidians started the fire.
Arson investigators found that gasoline, charcoal lighter fluid and camp stove fuel had been poured inside the compound.
In other developments, the Texas Department of Public Safety told The Dallas Morning News members of the Army's secret Delta Force anti-terrorism squad were at the scene the day the compound burned.
The newspaper obtained a Defence Department document under the Freedom of Information Act that confirmed the presence of the Special Forces unit when the FBI used tanks to assault the compound.
The US military is barred from domestic law enforcement.
Republican law said they would reopen the investigation and reconvene hearings into the incident.
The revelation "casts doubt on the entire testimony that the government gave Congress in 1995," Republican Representative Bob Barr told CNN.
