The Swiss embassy in Iran represents also the US interests, as Washington has no mission in the country since 1980, after Iranian students took 52 Americans hostage for 444 days.
Evidence, Presented by the US
The US envoy to UN has accused Iran of supplying Houthi rebels in Yemen with missiles, thus violating UN resolutions. Haley has presented what she said was the evidence of the claim, including remnants of an allegedly Iranian-made short-range ballistic missile, fired from Yemen at King Khaled International Airport outside Saudi Arabia's capital Riyadh in early November, as well as a drone and an anti-tank weapon recovered in Yemen by the Saudis.
However, the US envoy failed to specify when precisely the weapons were transported to the Houthis, she has expressed confidence that Tehran was standing behind these arms supplies, adding that they were "Iranian made, Iranian sent and Iranian given".
Iran has reacted to the statements, rejecting the "provocative and destructive" accusations made by the United States, comparing them to reports of US intelligence on weapons of mass destruction in Iraq.
The UN resolution, ensuring Iran's nuclear deal's correspondence with global powers, bans the country from supplying, selling or transferring arms abroad, unless agreed by the UN Security Council, with a separate UN resolution, prohibits the supply of weapons to Houthis in Yemen.
