Washington( CNN) The White House is demanding the liberate of all Americans currently being held in Iran and mentions President Donald Trump is “prepared to impose new and serious” outcomes on the two countries if they are not liberated and returned.

A statement released by the White House Friday said the Trump administration is “redoubling” its endeavour to bring home Americans “unjustly detained” abroad.

The statement mentioned three Americans specifically by name: Robert Levinson and Siamak and Baquer Namazi. Levinson has been held captive in Iran for over 10 years and The Namazis were taken during the course of its Obama administration, according to the statement.
