Any Iranian transfer of ballistic missiles to Russia would mark a sharp escalation in the Ukraine war, the United States said on September 6 after reports that the two countries had deepened ties with such an arms transfer. White House National Security Council spokesman Sean Savett said the United States is alarmed by the reports. "Any transfer of Iranian ballistic missiles to Russia would represent a dramatic escalation in Iran's support for Russia's war of aggression against Ukraine," Savett said. Reuters reported in August that Russia was expecting the imminent delivery of hundreds of Fath-360 short-range ballistic missiles. The Wall Street Journal reported on September 6 that short-range missiles had been delivered to Russia from Iran.
