The United Nations says it is "deeply alarmed" by the imminent execution in Iran of Swedish-Iranian doctor and academic Ahmedreza Djalali, and called for an immediate halt to it.
Liz Throssell, spokeswoman for the UN High Commissioner for Human Rights, said in a statement on May 17 that the authorities in Tehran should revoke Djallali's death sentence immediately.
Djalali, a medical doctor and lecturer at the Karolinska Institute in Stockholm, was arrested in Iran in 2016 during an academic visit. Jalali specializes in disaster relief and has taught at European universities. Rights groups have condemned his detention.
He was accused of providing information to Israel to help it assassinate several senior nuclear scientists.
Iran has threatened to execute him by May 21.
"Use of the death penalty for espionage offenses is incompatible with international human rights law. Countries that have not yet abolished the death penalty may only impose it for the 'most serious crimes,' which is interpreted as crimes of extreme gravity involving intentional killing," Throssell said in the statement.
Many Western groups say the threat to execute Djalali is tied to the current trial of an Iranian in Stockholm for his alleged role in the mass execution and torture of political prisoners at an Iranian prison in the 1980s.
Tehran has denied the cases, which have strained relations between Iran and Sweden, are linked.
