WASHINGTON/TEHERAN/GAZA - US President Donald Trump said that US-Iran talks will continue to see whether a deal can be consummated, shortly after his closed-door meeting with visiting Israeli Prime Minister Benjamin Netanyahu at the White House on Wednesday.

"I have just finished meeting with Prime Minister Netanyahu, of Israel, and various of his Representatives," Trump said in a post on Truth Social.

"There was nothing definitive reached other than I insisted that negotiations with Iran continue to see whether or not a Deal can be consummated," Trump said. "If it can, I let the Prime Minister know that will be a preference. If it cannot, we will just have to see what the outcome will be."

He added that the two leaders discussed the progress being made in Gaza and the region in general.

Netanyahu arrived at the White House in a vehicle via the South Lawn on Wednesday morning and left without a press conference or a statement issued.

The meeting, their seventh since the start of Trump's second term, reportedly lasted roughly three hours.

Before the meeting, Netanyahu met with US Secretary of State Marco Rubio and formally signed up as a member of the "Board of Peace." The initiative is controversial in Israel's parliament, Fox News reported.

Ahead of his trip to Washington, Netanyahu told reporters: "I will present to the president our concept regarding the principles of the negotiations (on Iran) -- the essential principles that are important not only to Israel but to anyone who wants peace and security in the Middle East."

Netanyahu's office has said that the prime minister wants the talks to include limits on Iran's ballistic missile program and cut Iran's ties with militant groups such as Hamas and Hezbollah.

Trump said on Tuesday in an interview with Fox Business Network that "it's got to be a good deal. No nuclear weapons, no missiles."

Iranian President Masoud Pezeshkian said at celebrations in Teheran for the 47th anniversary of the 1979 Islamic Revolution on Wednesday that a "wall of distrust" created by the West is hindering nuclear talks with the United States, vowing that Iran will never surrender to excessive demands and aggression.

Also on Wednesday, Iranian Foreign Minister Seyed Abbas Araghchi told Russia Today that he believes Iran and the United States can strike a nuclear deal better than the Joint Comprehensive Plan of Action signed in July 2015, while reiterating that Iran will not negotiate on its missile program or regional alliances.  

Washington and Teheran held their indirect talks on Friday in the Omani capital of Muscat amid simmering tensions between the two sides and a US military buildup near Iran.

On Tuesday, Trump said he is considering sending a second aircraft carrier strike group to the Middle East for possible military actions against Iran if negotiations fail.

Iran: no clear proposal received from US

A top Iranian security official said on Wednesday that Teheran has yet to receive any clear proposal from the United States despite ongoing indirect negotiations.

Secretary of Iran's Supreme National Security Council (SNSC) Ali Larijani made the remarks in an interview with Qatar's Al Jazeera during a visit to Doha, commenting on the first round of renewed nuclear talks held in the Omani capital, Muscat, on Friday.

Larijani described the meeting as merely an exchange of messages and stressed that negotiations are still underway.

He welcomed regional efforts to support the talks and reiterated Iran's commitment to diplomacy.

Larijani characterized US participation as a shift toward a "rational path." 

Separately, Larijani told state-run Al-Alam news channel on Wednesday that consultations are underway to determine the date of the next round of indirect nuclear talks between Teheran and Washington.

Larijani met the same day in Doha with Qatar's Prime Minister and Foreign Minister Sheikh Mohammed bin Abdulrahman bin Jassim Al-Thani. Their discussions addressed the recent US-Iran talks, with the Qatari leader reaffirming Doha's support for peaceful solutions to enhance regional security and stability.

However, he warned that any US attack would draw retaliation against US military bases in the region.

Larijani reaffirmed that the talks are focused exclusively on Iran's nuclear program, not on other issues.

He ruled out the possibility of zero uranium enrichment on Iran's soil, citing domestic needs for energy and pharmaceuticals.

The SNSC chief also accused Israel of seeking to derail the negotiations and destabilize the region.

A 'wall of distrust' and Iran's 'red line' of missile program

Iran on Wednesday said a "wall of distrust" created by the West is hindering nuclear talks with the United States, reaffirming its readiness for diplomacy on its nuclear program while vowing not to compromise on its defense capabilities.

Iranian President Masoud Pezeshkian, speaking at celebrations in Teheran for the 47th anniversary of the 1979 Islamic Revolution, said that a "wall of distrust" created by the West and excessive US demands are impeding progress in nuclear talks with Washington.

"We believe that the region's problems can be resolved only by regional countries, not foreign states," he said, adding that Iran will never surrender to excessive demands and aggression.

During the nationwide celebrations, participants marched in cities across Iran, reaffirmed their allegiance to the national establishment, and condemned the "aggressive, destabilizing and criminal" policies of the United States and Israel, which they blame for regional insecurity.

The 1979 Islamic Revolution, led by Ayatollah Ruhollah Khomeini, overthrew the US-backed Shah Mohammad Reza Pahlavi and transformed Iran into an Islamic republic.

Also attending the Wednesday celebrations in the capital, Ali Shamkhani, senior advisor to Iranian Supreme Leader Ali Khamenei, said Iran's missile capability is a red line and a non-negotiable issue.

According to a report by Iran's Nour News, Shamkhani said any military attack, even limited, will be considered the start of a war, the consequence of which will "reach a scope beyond the military dimension" and "affect the lives of people in different parts of the world."

Meanwhile, another report by Nour News published Wednesday, citing Iran's Foreign Ministry spokesperson Esmaeil Baghaei, said that Iran is willing to discuss the level of its uranium enrichment and the amount of its stockpile, only if its rights under the Nuclear Non-Proliferation Treaty are truly respected.

Hamas says any aggression against Iran constitutes 'criminal violation'

Al-Qassam Brigades, the armed wing of Hamas, said on Wednesday that any aggression against Iran would constitute a "criminal violation" of the sovereignty of the Islamic state.

In a press statement, Al-Qassam Brigades spokesperson Abu Obeida expressed full confidence in the determination and capability of the Iranian armed forces to repel any aggression and exercise their legitimate right to self-defense.

The statement followed a meeting held in Doha on Wednesday between a Hamas leadership delegation headed by Muhammad Darwish, chairman of the group's leadership council, and Ali Larijani, secretary of Iran's Supreme National Security Council, to discuss the latest regional developments.

During the meeting, Darwish reiterated Hamas' solidarity with Iran and rejected any attack on its territory, warning that aggression against Iran or any regional country would undermine security and stability.

For his part, Larijani briefed the Hamas leadership on the latest developments in Iran and ongoing negotiations with the United States, reiterating his country's firm support for the Palestinian cause.
