Islamic Republic’s Foreign Minister Mohammad Javad Zarif said on Wednesday that U.S. accusations against Iran related to Houthi missile attacks on Saudi Arabia are unfounded and Iran will pursue the matter with the U.N. Security Council.

Zarif told Iran’s official news agency, IRNA, that he has informed U.N. Secretary General Antonio Guterres of Iran’s protest on Tuesday, December 19.

Zarif was speaking in Baku, where the fifth round of discussions among the foreign minister of Iran, Turkey and Azerbaijan is taking place.

On Tuesday, a ballistic missile fired from Yemen targeted Saudi Arabia’s capital Riyadh, which was intercepted by Patriot missiles.

Later on Tuesday, U.S. permanent representative to the U.N., Nikki Haley told the Security Council that the missile fired "bears all the hallmarks of previous attacks using Iranian-provided weapons".

"We must all act cooperatively to expose the crimes of the Tehran regime and do whatever is needed to make sure they get the message. If we do not, then Iran will bring the world deeper into a broadening regional conflict," Haley told the council.

Zarif had responded on Tuesday, saying that “This actions by the Americans is provocative…and dangerous”.

Iran’s foreign ministry spokesman also rejected any weapons link with Yemen and said, “Iran has sufficient courage to announce it is providing weapons to Shiite Houthis if it had actually dome so”.

In her condemnation of Iran’s actions, Haley also announced she was exploring, with some council members, options for pressuring Iran to “adjust their behavior”.

"We could hold the IRGC (Iran's Islamic Revolutionary Guard Corps) accountable for its violations of numerous Security Council resolutions." A U.N. resolution on Yemen bans the supply of weapons to Houthi leaders and "those acting on their behalf or at their direction."
