The United States has formally accused Iran of providing short-range ballistic missiles to Russia for use in the ongoing war in Ukraine. US Secretary of State Antony Blinken made the announcement during a visit to London on Tuesday, stating that Russia had already received shipments of the missiles and would likely deploy them in the coming weeks against Ukrainians.

According to Blinken, the supply of Iranian missiles enables Russia to expand its arsenal and target areas further from the front line of the conflict. The United States, in response, has imposed fresh sanctions on Tehran, joining earlier sanctions that have already heavily burdened Iran's economy.

However, Iran has vehemently denied these allegations, stating that it considers providing military assistance to the warring parties as inhumane, leading to increased casualties and destruction. Iran's mission to the United Nations issued a statement calling for other countries to cease the supply of weapons to the conflicting sides.

During a news conference, Iranian Ministry of Foreign Affairs spokesperson Nasser Kanaani rejected the claims made by the US, highlighting that Iran itself abstains from engaging in such actions and reaffirming that Iran is not involved in the war in Ukraine. Kanaani further criticized the US, accusing it of being among the biggest arms exporters to one side of the conflict.

In response to the alleged missile transfers, the US Treasury and State Department have imposed sanctions on ten individuals and nine entities based in Iran and Russia. These sanctions freeze any US assets held by the targeted individuals and entities, deny them access, and generally prohibit Americans from engaging in transactions with them.

Included in the recent sanctions are ships that regularly transport cargo between Iran and Russia across the Caspian Sea. The Port Olya-3, a vessel owned by Russia-based company MG-FLOT, has been identified as one such ship that was used to transport close-range ballistic missiles. Ship tracking data revealed that the vessel made multiple trips between Olya, Russia, and Amirabad, Iran, between May and August of this year.

The State Department has also targeted Iran Air, as it was allegedly involved in procuring sensitive Western-origin goods and transporting materials for Iran's drone program. France, Germany, and Britain have expressed their support by canceling air services agreements with Iran and vowing to impose sanctions on Iran Air and those involved in Iran's ballistic missile program and supplying arms to Russia.

The accusations of Iranian missile transfers have the potential to embolden Ukrainian President Volodymyr Zelenskyy to push for further support from the US and other allies. Zelenskyy may seek authorization to use Western-supplied missiles to target Russian sites deep within its territory and thwart aerial attacks launched by Moscow.

As US officials Blinken and British Foreign Secretary David Lammy prepare for a joint visit to Ukraine, where they will meet with President Zelenskyy and other senior officials, discussions on strengthening the country's defense capabilities are set to take place. Lammy has described the Iranian missile transfers to Russia as a troubling pattern and a significant escalation.

The US accusation against Iran and the subsequent imposition of sanctions represent the latest development in the complex and volatile conflict in Ukraine. The international community closely observes how this will impact the dynamics of the war and whether it will prompt further actions or negotiations in the search for a resolution.
