Iran will not give up its right to enrich uranium while Israel prepares to attack it.

A senior Iranian official told Reuters on Thursday that Iran will not give up its right to enrich uranium due to escalating tensions in the region, adding that a "friendly" regional country had warned Tehran of a possible Israeli military strike. The official explained that these tensions aim to "influence Tehran to change its position on its nuclear rights" during talks with the United States on Sunday in Oman.

For its part, the International Atomic Energy Agency announced on Thursday that Iran is not complying with its nuclear non-proliferation obligations, marking the first time the UN agency has issued a resolution against Tehran in 20 years.

The long-awaited vote by the IAEA's Board of Governors in Vienna comes at a time of heightened tensions over Tehran's nuclear program, with US and European officials expressing their belief that Israel may be preparing an imminent military strike against Iran.

The agency confirmed that Iran has consistently failed to provide information about undeclared nuclear materials and activities at multiple locations.

The resolution was introduced by the United States, the United Kingdom, France, and Germany, and passed easily with 19 votes in favor of the resolution out of 35 countries on its Board of Governors. Russia, China, and Burkina Faso voted against the resolution, 11 other countries abstained, and two countries did not vote at all.

This comes as the United States anticipates a possible Israeli attack on Iran. The Washington Post reported that the United States is on high alert in the Middle East, anticipating a possible Israeli attack on Iran. Amid this anticipation, the United States is reducing the presence of its non-essential personnel in the region.

The report noted that "in recent months, US intelligence officials have grown increasingly concerned about the possibility that Israel might choose to strike Iranian nuclear facilities without US approval."

US officials told The Associated Press on Wednesday that the military has allowed the "voluntary departure" of families of US troops from locations across the Middle East.

The United States is also evacuating its staff from its embassy in Iraq. CBS News reported that Israel has informed the United States that it is "fully prepared to launch an operation in Iran," and that US officials are concerned that Iran may respond by striking US sites in Iraq.

The US State Department authorized the departure of non-essential staff from its embassies in Kuwait and Bahrain, giving them the option to leave rather than face mandatory evacuation.

This news came after Iran's defense minister warned that Tehran would strike US bases in the region if a "conflict" were imposed on Iran. Iranian officials had previously stated that they would hold the United States responsible for any Israeli attack, given its extensive military support for Israel.

Previous reports indicated that Israel is considering attacking Iran to disrupt negotiations between the United States and Iran. According to the New York Times, Israeli officials close to Prime Minister Benjamin Netanyahu believe that "the United States will have no choice but to assist Israel militarily if Iran launches a counterattack."

The current tensions come as Netanyahu faces a political crisis, with hardline parties threatening to dissolve the Knesset over the lack of an exemption bill for Israel's ultra-Orthodox Jews, although according to recent reports, the crisis may be defused.

President Trump has also threatened to bomb Iran if he fails to reach a nuclear agreement, and continues to publicly demand an end to Tehran's uranium enrichment program, something Iranian officials reject. In an interview published Wednesday, Trump said he is "less confident" that a deal with Iran is possible. According to a recent report from Axios, Trump has given Iran a deadline of June 12, Thursday, to reach an agreement.

In another indication that the United States may be preparing to take military action or support an Israeli attack on Iran, General Michael Kurilla, commander of U.S. Central Command (CENTCOM), postponed his scheduled testimony before Congress on Thursday due to tensions in the Middle East.

Amid reports of the United States evacuating its embassy in Baghdad, Iran's mission to the United Nations confirmed in a post on Twitter that Tehran is not seeking to acquire a nuclear weapon.

"Threats of 'overwhelming force' will not change the facts: Iran is not seeking a nuclear weapon, and US militarism only fuels instability," the mission said. "Diplomacy—not military action—is the only way forward."
