U.S. Ambassador to the United Nations Nikki Haley unveiled previously classified information to prove Iran violated United Nations Security Council Resolution 2231 by providing the Houthi rebels in Yemen with arms during a press conference at Joint Base Anacostia in Washington on Dec. 14, 2017. Haley said Thursday that a missile fired by Houthi militants at Saudi Arabia last month had been made in Iran.

The Defense Intelligence Agency concluded that both were Iranian Qiam short-range ballistic missiles. Some of the wear on the missiles analyzed by U.S. intelligence, including evidence that the missiles have been welded back together, supported their assessment that at least the Nov. 4 missile had been cut in half to more easily transport into Yemen.

The Defense Intelligence Agency said that the logo branded into the missile actuators belongs to Iranian manufacturer Shahid Bagheri Industries.

Houthi rebels, who are in a civil war with Yemen’s government and have been targeted for more than a year during a Saudi-led and U.S.-supported air campaign, claimed responsibility for the Nov. 4 ballistic missile launch.

The combined evidence, U.S. Ambassador to the United Nations Nikki Haley said Dec. 14, showed “unequivocally that these weapons were supplied by the Iranian regime.” The Defense Intelligence Agency reassembled drones and recovered parts of remotely controlled explosive boats it said Iran used to strike the Saudi frigate HMS Al-Madinah in the Red Sea on Jan. 30.
