She was there to present what the USA describes as recovered pieces of a missile fired by Houthi militants from that November 4 attack, pointing out the missile bears "Iranian missile fingerprints".
World powers that joined the USA in brokering that deal have voiced frustration at Mr. Trump's moves to "decertify" Iran's compliance with the deal as a prelude to renegotiating it. In addition, the deputy commander of the IRGC's Qods Force, Esmail Ghani, said: "Those defending Yemen have been trained under the flag of the Islamic Republic."Statements by the United Nations and USA, as well as reports by intelligence agencies, are significant because they corroborate and substantiate what Saudi leaders have previously pointed out, that Houthi missiles targeting Riyadh were made by Iran". Haley also showed parts the Defense Department said were from an attack in July on an oil refinery in Saudi Arabia as further evidence that Iran "is defying the global community, and not just one time". "The threat of Iranian missiles stretches from the Persian Gulf, through Yemen, Syria and all the way to Lebanon and Gaza".
Saudi-led forces, which back the Yemeni government, have been fighting the Iran-allied Houthis in Yemen's more than two-year-long civil war.
The officials said the materiel was handed over by the governments of Saudi Arabia and the United Arab Emirates and that there was no doubt about its provenance, even though in some cases USA officials did not have specific information on where the materiel was recovered.

The Associated Press and Agence France-Press have reported that United Nations officials examined debris from the missiles and said it pointed to a "common origin", but they could not conclude that they came from an Iranian supplier.
In an earlier tweet late Thursday, Zarif rejected US Ambassador to the UN Nikki Haley's remarks over the Islamic Republic's missile support for Yemen, comparing them to US claims in 2003 that Iraq possessed weapons of mass destruction (WMD).
A separate team of United Nations experts who inspected the missile fragments during a visit to Riyadh last month found a possible link to an Iranian manufacturer, the Shahid Bagheri Industrial Group, which is on the United Nations sanctions blacklist. Influential Iranian cleric Mehdi Tayeb said this has been carried out in stages by the IRGC with the support of the navy. It is not a coincidence that the US ambassador held her today's press conference two days after her claim in her interview with CNN, claiming that the common fight against Iran is much more important for the American regional allies than the plights of the Palestinians and the recognition of Jerusalem as Israel's capital.
Haley promised that the presentation is just the beginning of showcasing "uncomfortable" evidence of Iran's destabilizing activities. Iran is operating through and supplying the Houthis in Yemen, officials said.
The events of the past few weeks have both emboldened the Houthis and stiffened the determination of the Saudi-led coalition to defeat them at any cost, analysts said.
The report from UN Secretary-General Antonio Guterres, obtained by AFP, said officials were still analysing the information.
