WASHINGTON (Reuters) – The United States issued a pre-emptive warning to Iran on Thursday against pursuing three planned space rocket launches, which it said would violate a U.N. Security Council resolution related to its ballistic missile activity.

Secretary of State Mike Pompeo said Iran had announced plans to launch in the coming months three rockets, called Space Launch Vehicles (SLV), which he said incorporate ballistic missile technology.

“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.”

Pompeo said such rocket launches would violate United Nations Security Council Resolution 2231, which endorsed a 2015 nuclear deal between Iran and world powers. It calls upon Iran not to undertake activities related to ballistic missiles capable of delivering nuclear weapons, including launches using such technology. It stops short of explicitly barring such activity.

U.S. President Donald Trump decided in May to pull out of the Iran nuclear deal.

Pompeo said Iran has launched ballistic missiles numerous times since the U.N. resolution was adopted. He said it test-fired a medium-range ballistic missile capable of carrying multiple warheads on Dec. 1.

“The United States has continuously cautioned that ballistic missile and SLV launches by the Iranian regime have a destabilizing effect on the region and beyond,” Pompeo said. “France, Germany, the United Kingdom, and many nations from around the world have also expressed deep concern.”

In July 2017, Iran launched a rocket it said could deliver a satellite into space, an act the U.S. State Department called provocative. Earlier that month, the United States slapped new economic sanctions on Iran over its ballistic missile program.

Iran says its space program is peaceful, but Western experts suspect it may be a cover for developing military missile technologies.
