"The old issue raised by a court in Kuwait and linked to the Islamic Republic of Iran is a plan pursued by those malevolent (forces) that do not desire good relations between the two countries," Salehi was quoted as saying by IRNA.

"This (plan) is nothing but a conspiracy aimed at creating discord between Islamic countries in the region," he added. On Tuesday a Kuwait City court sentenced to death two Iranians and a Kuwaiti national for allegedly belonging to an Iranian spy ring.
