Alireza Akbari, a dual British-Iranian citizen and former Iranian official, has been executed, the Iranian judiciary-affiliated outlet Mizan reported on Saturday.

He was hanged for crimes including “corruption on earth,” according to tweets from Mizan, which did not specify when the execution took place.

Two tweets by the outlet Saturday accused Akbari of “extensive cooperation with British intelligence officers” for which he received “huge sums of money.”

Akbari’s death sentence was announced just days ago, on January 11, after he was convicted of spying for the United Kingdom. Akbari had denied the charges.

According to allegations published in Mizan on Wednesday, Akbari had been arrested “some time ago” for “spying against this country.”

“On this basis and after filing an indictment against the accused, the file was referred to court and hearings were held in the presence of the accused’s lawyer and based on the valid documents in this person’s file, he was sentenced to death for spying for the UK,” Mizan said.
