Several Kuwaiti MPs yesterday blasted neighbouring Iran over an espionage cell allegedly busted by the emirate's security forces, calling on the government to expel Tehran's ambassador.

"We call for freezing all agreements with Iran... The government should recall our ambassador from Tehran and expel the Iranian ambassador from Kuwait," hardline Salafi MP Mohammad Hayef told reporters.

Mr Hayef, who is well known for his anti-Iran stance, blasted the government for its silence, and warned that if it does not clarify its position "we will call for a special debate in parliament over the spy cell."

Citing a high-ranking security source, Al-Qabas daily reported on Saturday that security agencies had dismantled a spy cell working for Iran's elite Revolutionary Guards Corps.

The Iranian embassy has denied the information in the report.

Independent MP Shuaib al-Muwaizri, the spokesman for parliament's interior and defence committee, called for the expulsion of the Iranian envoy in Kuwait "if the news about the spy cell is proved."

"We hope that the government releases a statement on the issue and if it is true, the government must act decisively by asking the Iranian ambassador to leave Kuwait," Mr Muwaizri told reporters.

Parliament speaker Jassem Al-Khorafi said he preferred to wait for a government statement, but added that he still hoped that Iran is not involved in the issue.

Later yesterday, the government broke two days of silence but said only that investigations were under way and will be referred to court when they are completed, without providing details or naming Iran.

"Security agencies investigate whatever information they receive, including what has been reported lately," government spokesman Mohammed al-Baseeri said in a statement cited by the official Kuna news agency.
