In Washington, US counter-terrorism officials have strongly disputed the report by a Pakistani provincial minister that sons of Osama bin Laden have been arrested in south-eastern Afghanistan.
They said they had no information that would suggest any of the sons had been detained.
“They were arrested from Rabat area in Afghanistan,” Zehri told The Associated Press in a telephone interview.
Sources claim bin Laden has at least 23 children by several wives.
Saad is one the oldest, in his early 20s and has emerged as an al-Qaida leader and one of America’s top two dozen targets in the network.
Mohammed and Ahmed bin Laden also support their father’s efforts, US officials say.
