Secretary of State Antony J. Blinken and his special envoy for Iran, Robert Malley, said Monday that Iran should let the father travel abroad for treatment.
“Baquer Namazi needs immediate surgery, and the Iranian government should allow him the medical attention necessary to save his life,” Mr. Blinken said in a Twitter posting. “It’s been almost six years since he’s seen his children.”
Iranian officials have not said whether they will grant the father permission to leave. Iran’s Mission to the United Nations declined requests for comment.
At least two American citizens besides the Namazis are held in Iran on murky charges of spying and threatening national security. Morad Tahbaz, 66, a businessman and conservationist, has been detained since 2018. Emad Sharghi, 56, a businessman, was arrested in January.
Iran and the United States had been engaged in indirect negotiations for a prisoner exchange, but those efforts were suspended when talks over reviving the 2015 nuclear deal were halted in June.
The outlook for progress on the nuclear deal and a possible release of Americans in Iran remains unclear.
If the senior Mr. Namazi is prohibited from leaving Iran he will have the surgery there and has no restrictions on the doctor or hospital of his choice, his family said. But Covid-19 is rampant and medical facilities are overstretched. Moreover, the family said, he needs a stress-free recuperation. And Mr. Genser said Mr. Namazi’s insurance, Aetna, would not pay for medical costs in Iran.
