Family members of a father and son detained by Iran are appealing to President Joe Biden to make the freeing of Iranian American detainees a prerequisite in any deals with that country. Babak Namazi talked to reporters on Monday as his 84-year-old father, Baquer, marks his fifth year held in Iran. One of Babak Namazi’s brothers was detained by Iran in 2015. Iran took their father into custody when he flew to Tehran the next year seeking his son’s release. Babak Namazi says the Obama and Trump administrations failed to make a priority of winning their release. He says he’s encouraged by the Biden administration’s statements so far.
