Secretary of State Mike Pompeo said that Iran's satellite-delivery rockets used technology "virtually identical" to nuclear-capable ballistic missiles, which could eventually include long-range missiles capable of reaching the United States.

"The United States will not stand by and watch the Iranian regime's destructive policies place international stability and security at risk," Pompeo said in a statement.

"We advise the regime to reconsider these provocative launches and cease all activities related to ballistic missiles in order to avoid deeper economic and diplomatic isolation," he said.

Iran's deputy defense minister, Brigadier General Ghasem Taghizadeh, said in November that the clerical regime would launch three satellites into space "in the coming months."

"These satellites have been built with native know-how and will be positioned in different altitudes," he said, as quoted by the semi-official ISNA news agency.

Iran has seen economic potential in developing a satellite program, which could build a needed revenue source and also be used for espionage.

But US intelligence has said that the technology could easily be converted to long-range missiles.

Pompeo said that an Iranian launch would defy UN Security Council resolution 2231 of 2015, which endorsed an international accord on ending the clerical regime's nuclear program an called on Tehran to end ballistic missile launches.

US President Donald Trump last year walked out of the Iran deal, which was negotiated by his predecessor Barack Obama, instead reimposing sweeping sanctions aimed at crippling the country's economy.

European powers still support the accord, noting that Iran is in compliance, while sharing concern about missiles.
