The United States today denounced Iran’s “nuclear escalation” and responded by announcing sanctions aimed at hitting its oil sector, ahead of presidential elections in the Islamic Republic.

Iranians are voting tomorrow, Friday, to replace late President Ebrahim Raisi, who was killed in a helicopter crash in May.

“Over the course of the past month, Iran has announced measures aimed at further expanding its nuclear program in ways that do not have a credible peaceful purpose,” US Secretary of State Anthony Blinken said in a press release. “We remain committed to never letting Iran obtain a nuclear weapon, and we are prepared to use all elements of national power to ensure that outcome.”

“The steps taken by Iran to increase its enrichment capacity are all the more troubling given that Iran continues to be non-cooperative with the International Atomic Energy Agency (IAEA) and that statements by Iranian officials imply that its nuclear doctrine Iran could change,” he added.

Sanctions imposed “in response to Tehran’s nuclear escalation” target three United Arab Emirates shipping companies carrying Iranian oil and petrochemical products, according to the press release.

The sanctions also target 11 vessels linked to these three companies which become frozen goods.

The three shipping companies in question are Sea Route Ship Management, Almanac Ship Management and Al Anchor Ship Management.

The IAEA recently stated that Iran continues to increase its nuclear capabilities, enriching uranium to the high level of 60% while continuing to accumulate large stockpiles of uranium.

The United States and Western powers fear Tehran is trying to develop a nuclear weapon, which Iran denies.

On Tuesday, Washington imposed economic sanctions against a shadow banking network linked to Iran’s Islamic regime that aims to circumvent sanctions and provide access to the international banking system.

The specific sanctions mean that these entities are no longer authorized to conduct financial transactions with the United States and that any assets they may have are frozen.
