US President Donald Trump threatened Iran on Monday with bombing and secondary tariffs if Tehran does not reach an agreement with Washington over its nuclear program, Reuters reported.
In a telephone interview with NBC News, Trump said that US and Iranian officials had spoken, but he did not provide details.
"If they don't make a deal, there will be bombing. But there's a chance that if they don't make a deal, I'll impose secondary tariffs on them like I did four years ago," Trump said.
Trump also said he would impose secondary tariffs of 25 to 50 percent on all Russian oil if he believes Moscow is blocking his efforts to end the war in Ukraine, and they could begin within a month if there is no ceasefire.
Trump told NBC News that he was also angry when Russian President Vladimir Putin criticized the credibility of Ukrainian President Volodymyr Zelensky's leadership, NBC reported, citing Reuters.
Trump also said he plans to speak with Putin this week.
In his first term, which ran from 2017 to 2021, Trump withdrew the United States (US) from a 2015 agreement between Iran and world powers that placed strict limits on Tehran's disputed nuclear activities in exchange for sanctions relief.
Trump also reimposed harsh sanctions.
Since then, the Islamic Republic has far exceeded agreed limits in its escalating uranium enrichment program, according to Reuters.
Tehran has so far rejected Trump's warning to reach a deal or face military consequences.
Iran has sent a response via Oman to Trump's letter calling for a new nuclear deal, Iranian Foreign Minister Abbas Araqchi said on Thursday, the official IRNA news agency reported.
Western powers accuse Iran of having a secret agenda to develop a nuclear weapons capability by enriching uranium to a high level of purity, beyond what they say is justified for a civilian atomic energy program.
Tehran says its nuclear program is entirely for civilian energy needs.
During his presidential campaign for the 2024 election, Trump repeatedly promised to end what he calls the "ridiculous" war in Ukraine, and he has focused heavily on the issue since taking office on January 20 of this year, according to Reuters.
The agency states that Trump himself called for new elections in Ukraine and falsely called Zelensky a dictator.
Putin suggested on Friday that Ukraine could be placed under a form of interim administration to allow for new elections and the signing of key agreements, which could effectively oust Zelensky.
"If Russia and I cannot reach an agreement to stop the bloodshed in Ukraine, and if I think it was Russia's fault... I will impose secondary tariffs on oil, on all oil coming out of Russia," Trump said.
He said that tariffs on Russian oil would come within a month if there was no ceasefire agreement.
Trump said Putin knows he's angry with him, but said he had a "very good relationship with him" and that "the anger goes away quickly... if he does the right thing."
