LOS ANGELES, June 28: Two men who work in New York for Iran’s mission to the United Nations are being expelled from the United States, ABC News said on Friday.

Sources told the netwrok that the two Iranians were seen five days ago videotaping the Brooklyn Bridge, the entry point to the tunnels into Manhattan and the Statue of Liberty.

The men, who have been in the United States only four months and are described as security workers for the mission, were stopped and questioned by New York police, sources said, but were not arrested because of their diplomatic immunity.

US officials plan to expel the men for suspicious activities, some of which are related to irregularities in their identification documents, sources said.

A spokesman for the Iranian consulate in New York said the two individuals were filming each other and were briefly questioned by a New York police officer and released.

The spokesman said neither person had been expelled nor had the consulate received word from the US government or any other authority that there is a plan to expel the two men.

The expulsion of the two Iranians reflects the nationwide tightening of security as the July 4 holiday approaches.

Officials told ABC News the Pentagon was preparing to dramatically increase its combat air patrols over a dozen cities during the holiday week.
