STOCKHOLM — Iranian Foreign Minister Mohammad Javad Zarif said on Wednesday Tehran "will do its best" to see if the death sentence on Swedish-Iranian scientist Ahmadreza Djalali can be delayed.

Djalali, a medical doctor and lecturer at the Karolinska Institute in the Swedish capital, was arrested in Iran in April 2016 and later convicted of espionage, having been accused of providing information to Israel to help it assassinate several senior nuclear scientists.

Iran’s Supreme Court upheld the death sentence in December 2017 and Tehran prosecutor Abbas Jafari Dolatabadi said Djalali had confessed to meeting agents of Israeli intelligence agency Mossad to deliver information on Iran’s nuclear and defense plans and personnel.

"We will do our best on humanitarian grounds to see if the sentence on Mr. Djalali can be delayed, but he has been accused of multiple capital crimes... and he has been convicted of them," Zarif said in response to a reporter's question after giving a lecture at the Stockholm International Peace Research Institute during a visit to Sweden.

"In Iran the judiciary is independent," Zarif added. "Today two members of the Iranian Cabinet are being tried by our judiciary. That shows you how independent the judiciary is from our executive."

Sweden granted citizenship to Djalali in February 2018. Its foreign ministry said it has requested access to Djalali and has called for the death penalty not to be implemented.

Djalali had been on a business trip to Iran when he was arrested and sent to prison. Human rights campaigner Amnesty International has said he was held in solitary confinement for three months and tortured. — Reuters
