Manama: Kuwait's Court of Appeals on Monday postponed the trial of an alleged pro-Iran espionage ring to March 5.
The seven defendants were charged with spying for Iran and of passing on information on the Kuwaiti and US military in Kuwait to Iran's Revolutionary Guards.
The criminal court on March 29 sentenced two Iranians and a Kuwaiti national to death. A Syrian and a stateless Arab were given life in prison.
The court in Kuwait City acquitted the only woman, the daughter of one of the men on the death row, and another Iranian suspect.
Tehran denied the charges and said there was nothing to spy on in Kuwait.
Around 45,000 Iranians live in Kuwait.
