Iran on Monday announced the execution of a man convicted of spying for the United States and Israel, in what appears to be part of a broader rise in executions linked to security-related offences amid ongoing regional tensions.

According to the judiciary-affiliated Mizan Online news agency, Erfan Shakourzadeh was executed after being found guilty of collaborating with the US Central Intelligence Agency (CIA) and Israel’s Mossad intelligence service.

Mizan reported that Shakourzadeh worked for one of Iran’s scientific organisations involved in the satellite sector, though authorities did not disclose the date of his arrest or execution. The report alleged that he had “knowingly and willingly” provided classified information to the two foreign intelligence agencies.

Iran’s satellite programme has long drawn scrutiny from Western governments, which accuse Tehran of using the initiative to support the development of ballistic missile technology. Iranian officials have consistently denied the allegations, maintaining that the programme is intended for peaceful and civilian purposes.

The execution comes amid heightened hostilities involving Iran, Israel, and the United States. Although a ceasefire reportedly took effect on April 8, Iran has intensified the use of capital punishment in cases tied to alleged espionage and national security threats since the conflict began in late February.

Human rights organisations have repeatedly criticised Iran’s extensive use of the death penalty. According to Norway-based group Iran Human Rights, the Islamic Republic carried out at least 1,500 executions last year, making it one of the world’s leading executioners after China.

Last week, Iranian authorities also executed three men convicted over their alleged involvement in anti-government protests that swept the country in December and January.
