Blinken says the $6bn frozen funds released to Iran under the prisoner swap deal have always been available to Tehran for humanitarian purposes.
He says "technical reasons" meant Iran was not able "to access those funds where they were".
Blinken says the funds were moved to another bank "where we have absolute oversight of how they're used, and they can only be used for humanitarian purposes."
He says the US has "absolute confidence" in the mechanisms in place to ensure the funds are used for humanitarian needs.
