U.S. officials believe Saad bin Laden — a son of Osama bin Laden — has been killed by an American missile in Pakistan.
Saad bin Laden reportedly spent years under house arrest in Iran before traveling last year to Pakistan, according to former National Intelligence Director Mike McConnell.
It's believed he was killed by Hellfire missiles fired from a U.S. Predator drone sometime this year.
A senior U.S. counterterrorism official tells NPR that without a body to conduct DNA tests on, it's hard to be completely sure. But he characterized U.S. spy agencies as being "80 to 85 percent" certain that Saad bin Laden is dead.
The U.S. counterterrorism official says Saad bin Laden wasn't important enough to target personally — that he was "in the wrong place at the wrong time."
He was active in al-Qaida, but was not a major player, the official said. He was believed to be in his late 20s.
"We make a big deal out of him because of his last name," the official added.
It's not known whether Saad bin Laden was anywhere near his father when he died.
