Iranian authorities on Tuesday executed a man convicted of allegedly collaborating with and spying for Israel’s Mossad intelligence agency, according to the judiciary.

"Gholamreza Khani Shakarab was executed on charges of intelligence cooperation and espionage in favor of the Zionist regime," the judiciary's Mizan Online website reported, adding that his sentence was upheld by the Supreme Court, The Caspian Post reports, citing CBS news.

The hanging is the latest in a string of executions by the Islamic republic for security-related cases following the outbreak of war with Israel and the United States on Feb. 28.

Mizan described Shekarab as "one of the operational ringleaders of Mossad abroad ... who was seeking to recruit individuals inside the country" for "anti-security actions."

"Ultimately, in a complex operation and using intelligence deception tactics, the accused was guided into the country and arrested," it said, adding that he was detained by Islamic Revolutionary Guard Corps intelligence forces.

The report also said that Shekarab had been tasked by Israel's Mossad spy agency "to travel to one of the regional countries with the aim of identifying and preparing the groundwork for the assassination of a Jewish rabbi... to accuse Iran of anti-Jewish actions."

It was not immediately clear when Shekarab was arrested or sentenced.
