Iran has executed a former defense minister at the expense of espionage to the United States, state media report.
Jalal Hajizavar was sentenced by a military sentence after espionage equipment and documents were found in his home, according to the IRIB news agency.
He allegedly worked as a contractor for the Defense Ministry's aviation organization, but left the role nine years ago.
It comes at a time of escalating tensions between the United States and Iran.
Mr. Hajizavar was allegedly executed several days ago at the Rajaishahr prison in Karaj, close to the capital Tehran. He had "openly announced and accepted to spy for the Central Intelligence Agency [CIA] and receive money in return", IRIB reports.

On Tuesday Iran said it had disconnected a espionage network associated with the CIA and had arrested a number of spies, but it is not clear whether this is related to the performance of Mr. Hajizavar.

On Thursday, an unmanned American drone was shot down in the region. Tehran says it has entered Iranian airspace, but the United States insists it was shot down in international airspace.
US President Donald Trump has said he does not want war with Iran, but warned that it would be "wiped out" if conflict broke out.
