The Iranian president said his country would not be intimidated by threats as Trump accused Tehran of conducting a proxy war.

Iranian President Masoud Pezeshkian said his country would not “submit to any bullying” in response to criticism from U.S. President Donald Trump during his three-day Gulf tour.

He was broadcast live on state television on Wednesday, and he said: "He (Trump) thought he could come here and shout slogans and scare us. It's harder for us than lying in bed. Are you here to scare us? Are we not going to bow? We won't succumb to any bully."

Earlier in the day, at the GCC summit in Riyadh, Trump said that while he wanted to reach an agreement with Iran, the country "must stop sponsoring terror, stop its bloody proxy war, and permanently, prove to cease the pursuit of nuclear weapons."

Washington and Tehran held four meetings, mediated by Oman to help reach an agreement on the latter's nuclear program.

Trump repeated his open desire for Iran's nuclear program peace plan during a state dinner in the Catari capital in Doha on Wednesday and recommended the ball in Tehran court.

"It's a dangerous situation and we want to do the right thing," Trump said. "We want to do something that can save millions of lives. Because things like this start, they're out of control."

Trump said Tuesday he wanted to "conclude a deal with Iran" but "if Iran's leadership rejects this olive tree...we have no choice but to create huge maximum pressure." He added that he did not allow Iran to possess nuclear weapons.

The continuous U.S. government has tried to prevent Iran from obtaining nuclear weapons. During the Barack Obama administration, the continued efforts of world powers eventually reached a 2015 agreement called the Joint Integrated Action Plan (JCPOA).

But when Trump took over Obama as U.S. president, he unilaterally withdrew from the U.S. nuclear deal in 2018, causing the deal to collapse.

Despite the ongoing talks, the Trump administration continues to impose sanctions on Iran.

The U.S. imposed sanctions on Wednesday against Iran in an effort to build components of ballistic missiles for domestic use, the U.S. Treasury Department said.

The sanctions target six people and 12 entities, for what the Ministry of Finance calls “they are involved in the manufacturing of key materials needed to help the Iranian regime obtain Tehran’s ballistic missile program at home.”
