Omar bin Laden broke with his father in 2001 after living in Afghanistan for much of 1996 to 2001.
In an interview with Reuters in 2010, Omar said he was working with Saudi Arabia and Iran to end his separation from a group of brothers and sisters that dates back to the chaos in Afghanistan following the al Qaeda attacks of September 11, 2001.
