Global rights group Human Rights Watch urged Afghan officials to free the young son of Pakistani scientist Aafia Siddiqui, who is currently awaiting trial in the United States on charges of trying to kill US officials. Aafia Siddiqui, whose name is on a 2004 US list of suspects with links to Al Qaeda, was flown to the United States early this month, where she is currently in custody, accused of attempting to murder US officials who were sent to question her after her arrest by Afghan police.
