Iran said Monday the attacks launched on the Islamic republic during talks about its nuclear program were a "betrayal of diplomacy".

"We and future generations will not forget that the Iranians were in the middle of a diplomatic process with a country that is now at war with us," said foreign ministry spokesman Esmaeil Baqaei.

Iran's Foreign Minister Abbas Araghchi on Sunday condemned US attacks on key nuclear sites as "outrageous" and said his country has a right to defend its sovereignty.

"The events this morning are outrageous and will have everlasting consequences," he posted on X, adding that the attacks were "lawless and criminal" behaviour.

The U.N.'s International Atomic Energy Agency (IAEA) on Sunday said that it had not detected any increase in radiation levels at key nuclear sites in Iran following U.S. air strikes.

U.S. President Donald Trump said U.S. air strikes on Sunday "totally obliterated" Iran's main nuclear sites, as Washington joined Israel's war with Tehran in a flashpoint moment for the Middle East.

In a televised address to the nation from the White House, Trump warned that the United States would go after more targets if Iran did not make peace quickly.

U.S. President Donald Trump said overnight that Iran had a "maximum" of two weeks to avoid possible U.S. air strikes, indicating he could take a decision before the fortnight deadline he set a day earlier.

The success of a key NATO summit hung in the balance on Friday, after Spain announced that it cannot raise the billions of dollars needed to meet a new defense investment pledge demanded by U.S. President Donald Trump.

Trump and his NATO counterparts are meeting for two days in the Netherlands from next Tuesday. He insists that U.S. allies should commit to spending at least 5% of gross domestic product, but that requires investment at an unprecedented scale.

A Russian missile strike on a nine-story Kyiv apartment building was a sign that more pressure must be applied on Moscow to agree to a ceasefire, Ukrainian President Volodymyr Zelensky said Thursday, as Moscow intensifies attacks in the war.

The drone and missile attack on Kyiv early Tuesday, the deadliest assault on the capital this year, killed 28 people across the city and wounded 142 others, Kyiv Military Administration head Tymur Tkachenko said.

Fleeing Iran with her husband and toddler, Amena Namjoyan reached a rocky beach of this eastern Greek island along with hundreds of thousands of others. For months, their arrival overwhelmed Lesbos. Boats fell apart, fishermen dove to save people from drowning, and local grandmothers bottle-fed newly arrived babies.

Namjoyan spent months in an overcrowded camp. She learned Greek. She struggled with illness and depression as her marriage collapsed. She tried to make a fresh start in Germany but eventually returned to Lesbos, the island that first embraced her. Today, she works at a restaurant, preparing Iranian dishes that locals devour, even if they struggle to pronounce the names. Her second child tells her, "'I'm Greek.'"

Armenian Prime Minister Nikol Pashinyan is scheduled to hold talks with Turkish President Recep Tayyip Erdogan on Friday as part of the two countries' efforts to normalize ties that were strained over historic disputes and Turkey's alliance with Azerbaijan.

The talks between the two countries, which have no formal diplomatic ties, were expected to center on the possible reopening of their joint border as well as the war between Israel and Iran.

Israel and Iran exchanged strikes a week into their war Friday as President Donald Trump weighed U.S. military involvement and new diplomatic efforts got underway.

Trump has been weighing whether to attack Iran by striking its well-defended Fordo uranium enrichment facility, which is buried under a mountain and widely considered to be out of reach of all but America's "bunker-buster" bombs. He said he'll decide within two weeks whether the U.S. military will get directly involved in the war given the "substantial chance" for renewed negotiations over Tehran's nuclear program.
