Iran on Saturday imposed sanctions on 24 more Americans in a largely symbolic move, as months of talks to revive a 2015 nuclear deal have stalled.

Among those sanctioned are former Army Chief of Staff George Casey and former President Donald Trump's attorney Rudy Giuliani.

Almost all the people named were officials who served during Trump's administration, which imposed sanctions on Iranian officials, politicians and companies and withdrew the United States from Iran's nuclear agreement with world powers.

In a statement carried by local media, the Iranian Foreign Ministry accused the sanctioned Americans - who also included several business figures and politicians - of supporting "terrorist groups and terrorist acts" against Iran, and Israel's "repressive acts" in the region and against Palestinians.

Eleven months of indirect talks between Iran and the United States in Vienna on salvaging the 2015 deal have stalled as both sides say political decisions are required by Tehran and Washington to settle the remaining issues.

Gen. Austin Scott Miller, former commander of US forces in Afghanistan, former Commerce Secretary Wilbur Ross, and several former ambassadors are among the officials targeted by the new Iranian sanctions.

In a similar move announced in January, Iran imposed sanctions on 51 Americans, many of them from the U.S. military, over the 2020 killing of General Qassem Soleimani in a drone strike in Iraq.

Last year, it imposed sanctions on Trump and several senior US officials.
