UNITED NATIONS — U.S. Ambassador Nikki Haley urged the Security Council on Tuesday to punish Iran for what the Trump administration calls its “dangerous violations” of U.N. resolutions and “destabilizing behavior,” while Russia said dialogue is needed rather than threats or sanctions.

Haley told a council meeting on implementation of the resolution that endorsed the 2015 nuclear deal with Iran that in the coming days the U.S. will explore a number of options with council members to pressure the Iranians “to adjust their behavior.”

Haley said the council could strengthen the resolution, adopt a new one to prohibit all Iranian ballistic missile activity, explore sanctions “in response to its clear violation of the Yemen arms embargo,” and hold the Islamic Revolutionary Guard Corps accountable for violating numerous council resolutions.

While the United States “continues to uphold its commitments” under the nuclear agreement, she said the international community must take action to address Iranian actions such as its arms sales, ballistic missile launches and support for terrorism.

But Russia’s deputy U.N. ambassador, Vladimir Safronkov, said that what is needed to implement the resolution on the nuclear deal is “to abandon the language of threats and sanctions, and to start using the instruments of dialogue — and concentrate on broadening cooperation and mutual trust.”

The Security Council was discussing Secretary-General Antonio Guterres’ report on implementation of the 2015 resolution. The U.N. chief said Iran was complying with the nuclear deal with the U.S. and five other world powers, but he warned that Tehran may be defying a U.N. call to halt ballistic missile development.

Guterres said the United Nations is investigating Iran’s possible transfer of ballistic missiles to Houthi Shiite rebels in Yemen that may have been used in launches aimed at Saudi Arabia on July 22 and Nov. 4.

Safronkov stressed that the resolution makes no demand — it calls on Iran not to carry out ballistic missile activity that could be capable of delivering nuclear weapons.

He accused the U.N. Secretariat of carrying out investigations without prior Security Council approval, saying it “has neither the authority nor the expertise” and the information obtained “cannot be considered accurate.”

Safronkov said a Russian initiative for “a system of collective security” and confidence building measures in the Middle East is relevant today.
