Iran's foreign ministry on Tuesday slammed the new sanctions by the European Union and Britain against Tehran over its support for Russia's war on Ukraine as unjustified.

U.S. prosecutors announced charges on Friday in an alleged Iranian plot to assassinate former president Donald Trump and a prominent dissident Iranian-American journalist.

Iranian Foreign Ministry spokesman Esmaeil Baghaei said on Monday Tehran would "respond firmly and effectively" to deadly Israeli strikes on military sites over the weekend.

"We are using all available means to respond firmly and effectively to the aggression of the Zionist regime," Baghaei told a regular news conference.
