One of Osama bin Laden’s sons went missing in the midst of the Navy SEAL raid that took the life of the al Qaeda leader more than a week ago, Pakistani security officials told ABC News today.

The officials said bin Laden’s three wives, who are all in Pakistani custody, said that one of bin Laden’s sons has not been seen since the raid. The son has not been identified, but Pakistani investigators agreed that it appeared someone was missing from the sprawling compound, the officials said.

U.S. officials said that one of bin Laden’s sons, Khalid, was killed in the raid. It is not known if another son, Hamza, was in the compound at the time of the raid, though his mother is reportedly one of the wives in custody. The U.S. has denied the SEALs took anyone from the compound other than bin Laden’s body.

The U.S. initially faced resistance from Pakistani authorities when investigators asked for access to bin Laden’s widows, but a U.S. official said Monday Pakistani official promised to make the meeting happen sometime soon. One senior Pakistani security official told ABC News there is still no timeframe for that meeting, however.
