Osama bin Laden's son Sa'ad was probably killed by a US missile strike in Pakistan earlier this year, reports have said. Sa'ad bin Laden was a prominent figure in the murky relationship between Iran and al Qaeda.
It was believed he went to Pakistan after spending a number of years under house arrest in Iran, US intelligence officials said in January.
But a missile fired from a US drone aircraft is believed to have killed him sometime this year, US National Public Radio said citing an unnamed US counter-terrorism official.
US intelligence agencies were "80 to 85%" certain Sa'ad bin Laden was dead, the official said.
The son of the al Qaeda leader was not important enough to be targeted himself but was "in the wrong place at the wrong time", the official went on.
It was not clear whether Sa'ad bin Laden was near his father when he died, NPR added.
The official described Sa'ad as being active in al Qaeda, but not a major player. He was thought to be in his late 20s.
US forces have stepped up their drone attacks in Pakistan since last September, targeting Taliban and al Qaeda-linked militants in areas bordering Afghanistan.
America has carried out close to 50 such air strikes since the beginning of last year, killing about 470 people, including many foreign militants, according to a tally of reports from Pakistani intelligence agents and district government officials.
