A U.S. deportation flight of at least eight Iranian nationals who were eventually bound for Iran has been abruptly canceled. That's according to a legal group involved in a pending lawsuit that's shed some light on the planned deportations. Ali Rahnama is an attorney with the Iranian American Legal Defense Fund. He says at least eight Iranians were loaded onto a plane Sunday in Arizona bound for Pakistan. The Iranians were told they would then be transported to Iran. But Rahnama says the flight was then canceled without explanation. The U.S. Department of Homeland Security refused to comment on the details of removal operations.
