I thought one of Rahman's other sons was killed in Afghanistan, but I could be wrong (and DON'T dig for it). I know two of his sons were with bin Laden for years.
"The younger Abdel-Rahman was caught several weeks ago in Quetta, Pakistan, the officials said, speaking on condition of anonymity."
But......
Son of Convicted Terrorist Omar Abdel-Rahman Captured in Afghanistan - November 29, 2001
"Cairo lawyer Montasser el-Zayat, who defends Islamic militant suspects, said the captured son, Ahmed Abdel-Rahman was being held in the northern Afghan city of Mazar-e-Sharif and his interrogators included Americans. El-Zayat said forces in Afghanistan were looking for Ahmed's brother, Mohammed, who was also in the country."
What happened? Was he captured and released back in November 2001?
