The Pentagon has released the first images from the raid that led to the death of Abu Bakr al-Baghdadi, showing US forces obliterating resistance.
Video showed American special forces came under fire as they approached the building, and a helicopter took out the gunmen from the air.
Another video showed US Delta Force operators advancing on the compound across open ground.
A third film showed a missile strike that flattened the compound following the raid in north-west Syria at the weekend.
There were also before-and-after photographs, and a senior military official said the compound now resembled a “parking lot.”
General Frank McKenzie, head of US Central Command, said “fighters from two locations in the vicinity of the compound began firing on US aircraft participating in the assault” before they were destroyed.
He said four men and two women were killed by US forces inside the compound. Two children who were taken into a tunnel by Baghdadi as he fled were “under the age of 12,” he said.
General McKenzie said Baghdadi may have fired, or attempted to fire a weapon at US forces from the tunnel before detonating a suicide vest, killing himself and the two children.
“He crawled into a hole with two small children and blew himself up while his people stayed on the ground,” the general said. He could not confirm Donald Trump’s suggestion that Baghdadi was “whimpering and crying” in the moments before he died.
He also gave further details about a dog injured while chasing Baghdadi down the tunnel. The dog was hurt after encountering live wires in the passageway. It has completely recovered.
The animal is a four-year veteran of military service and has been involved in more than 50 combat missions, the general said.
General McKenzie said a DNA test showed “beyond a shadow of a doubt” that the dead man in the tunnel was Baghdadi.
It produced a “level of certainty that the remains belonged to Baghdadi of one in 104 septillion.”
Central Command confirmed Baghdadi was buried at sea.
