Iran’s Khamenei says ‘never surrender’; warns U.S. of ‘irreparable damage’ if it intervenes

Iran’s supreme leader Ayatollah Ali Khamenei said Wednesday (June 18, 2025) the nation would never surrender as demanded by U.S. President Donald Trump and warned the United States it would face “irreparable damage” if it intervenes.

“This nation will never surrender to imposition from anyone,” Ayatollah Khamenei said in a speech read on state television. “America should know that any military intervention will undoubtedly result in irreparable damage.”

The remarks from Ayatollah Ali Khamenei, who has only been seen once since the strikes began, came after Mr Trump demanded “UNCONDITIONAL SURRENDER” in a social media post and warned Ayatollah Khamenei that the U.S. knows where he is but has no plans to kill him, “at least not for now.”

Mr Trump initially distanced himself from Israel’s surprise attack on Friday (June 13, 2025) that triggered the conflict but in recent days has hinted at greater American involvement, saying he wants something “much bigger” than a ceasefire. The U.S. has also sent more warplanes to the region.

An Iranian official had earlier warned Wednesday (June 18, 2025) that U.S. intervention would risk “all-out war.”

Foreign Ministry spokesman Esmail Baghaei did not elaborate but thousands of American troops are based in nearby countries within range of Iran’s weapons. The U.S. has threatened a massive response to any attack.

Another Iranian official said the country would keep enriching uranium for peaceful purposes, apparently ruling out Mr Trump’s demands that Iran give up its disputed nuclear program.

The latest Israeli strikes hit a facility used to make uranium centrifuges and another that made missile components, the Israeli military said. It said it had intercepted ten missiles overnight as Iran’s retaliatory barrages diminish. The U.N. nuclear watchdog said Israel had struck two centrifuge production facilities in and near Tehran.

The Israeli military said it also carried out strikes in western Iran, hitting missile storage sites and a loaded missile launcher.

Israeli strikes have hit several nuclear and military sites, killing top generals and nuclear scientists. A Washington-based Iranian human rights group said at least 585 people, including 239 civilians, have been killed and more than 1,300 wounded.

Iran has fired some 400 missiles and hundreds of drones in retaliatory strikes that have killed at least 24 people in Israel and wounded hundreds. Some have hit apartment buildings in central Israel, causing heavy damage, and air raid sirens have repeatedly forced Israelis to run for shelter.

Iran has fired fewer missiles as the conflict has worn on. It has not explained the decline but Israel has targeted launchers and other infrastructure related to the missiles.

The Washington-based group Human Rights Activists said it had identified 239 of those killed in Israeli strikes as civilians and 126 as security personnel.

The group, which also provided detailed casualty figures during 2022 protests over the death of Mahsa Amini, crosschecks local reports against a network of sources it has developed in Iran.

Iran has not been publishing regular death tolls during the conflict and has minimized casualties in the past. Its last update, issued Monday (June 16, 2025), put the toll at 224 people killed and 1,277 others wounded.

Shops have been closed across Tehran, including in its famed Grand Bazaar, as people wait in gas lines and pack roads leading out of the city to escape the onslaught.

A major explosion could be heard around 5 a.m. in Tehran Wednesday (June 18, 2025) morning, following other explosions earlier in the predawn darkness. Authorities in Iran offered no acknowledgement of the attacks, which has become increasingly common as the Israeli airstrikes have intensified.

At least one strike appeared to target Tehran’s eastern neighbourhood of Hakimiyeh, where the paramilitary Revolutionary Guard has an academy.

Israel says it launched the strikes to prevent Iran from building a nuclear weapon, after talks between the United States and Iran over a diplomatic resolution had made little visible progress over two months but were still ongoing. Mr Trump has said Israel’s campaign came after a 60-day window he set for the talks.

Iran long has insisted its nuclear program was peaceful, though it is the only non-nuclear-armed state to enrich uranium up to 60%, a short, technical step away from weapons-grade levels of 90%. U.S. intelligence agencies have said they did not believe Iran was actively pursuing the bomb.

Israel is the only country in West Asia with nuclear weapons but has never publicly acknowledged them.

Iran’s ambassador to Geneva, Ali Bahreini, told reporters that Iran “will continue to produce the enriched uranium as far as we need for peaceful purposes.”

He rejected any talk of a setback to Iran’s nuclear research and development from the Israeli strikes, saying, “Our scientists will continue their work.”

He said Mr Trump’s remarks were “completely unwarranted” and “very hostile,” and that Iran could not ignore them. He said Iranian authorities were “vigilant” about the comments and would decide if the U.S. crossed any lines. “Once the red line is crossed, the response will come.”

Israelis began returning on flights for the first time since the country’s international airport shut down at the start of the conflict.

Two flights from Larnaca, Cyprus, landed at Tel Aviv’s Ben Gurion International Airport on Wednesday (June 18, 2025) morning, said Lisa Dvir, an airport spokesperson.

Israel closed its airspace to commercial flights because of the ballistic missile attacks, leaving tens of thousands of Israelis stranded abroad. The conflict has disrupted flight patterns across the region.
