Foreign Ministry spokesman Ramin Mehmanparast on Tuesday regretted the mistaken statement made by Kuwaiti Foreign Minister Kuwait's Foreign Minister Sheikh Mohammad Sabah as-Salim as-Sabah about Iran, IRNA reported.
Sheikh as-Sabah accused Iran of having links with the alleged spy network and interfering in Kuwaiti internal affairs.
Mehmanparast made it clear that Sheikh as-Sabah remarks are not in the interests of the regional nations.
Iran expects the regional countries' officials not to utter hasty remarks and adopt prudent and foresighted stances, he said.
Al-Sabah's statements were aired by the Kuwaiti media.
In reaction to the Kuwaiti baseless accusation against Iran, President Mahmoud Ahmadinejad told a press conference: 'What is there in Kuwait to make Iran spy for?'
In March, Kuwaiti judiciary officials repeated earlier claims of having dismantled what they called an Iranian spy cell.
The allegation was dismissed by the Iranian Foreign Ministry as "irresponsible."
Tehran also raised questions about the goals Kuwait was pursuing by renewing the allegations they had first made in 2010 but subsequently withdrew upon protests by Iranian officials.
