On 14 May, both Iranian and U.S. officials said they were not seeking war, even as threats and counter-threats continued. Ayatollah Khamenei downplayed the escalation, saying in comments carried on state television that "no war is going to happen," while Mike Pompeo said while on a visit to Russia, "We fundamentally do not seek a war with Iran." On the same day, Houthi rebels in Yemen carried out multiple drone attacks on a Saudi oil pipeline deep in Saudi territory. The U.S. stated that it believed Iran sponsored the attack, though it was unclear if the attack was particularly related to the Iran-U.S. tensions or related to the Yemeni Civil War that began in 2015 and the Saudi Arabian-led intervention there. On 15 May, the U.S. State Department announced that all non-emergency staff had been ordered to leave the U.S. Embassy in Baghdad.
