Six people including al-Zarqawi and a key lieutenant, spiritual adviser Sheik Abd-al-Rahman, were killed in the strike, the military said. Iraqi forces were the first to arrive at the scene, Caldwell said.
"Zarqawi's body was then removed, brought back to a secure location," Caldwell said. "By visual identification it was established that that probably was him.
"But they ... did further examination of his body, found more scars and tattoos consistent with what had been reported and what we knew about him. They then did a fingerprint identification, and that came back ... this morning as positively identified as Zarqawi having been killed."
"We have absolutely no doubt whatsoever that Zarqawi was in the house," Caldwell said. "It was 100 percent identification." Even so, DNA testing will be conducted, he said.
