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.

Thousands of people joined a protest against Israel in the Iranian capital on Friday after weekly prayers, chanting slogans in support of their leaders, images on state television showed.

"This is the Friday of the Iranian nation's solidarity and resistance across the country," the news anchor said. Footage showed protesters holding up photographs of commanders killed since the start of the war with Israel, while others waved the flags of Iran and the Lebanese militant movement Hezbollah.

French President Emmanuel Macron on Friday said France and other European powers would make an offer to Iran of a diplomatic solution to end the escalating conflict with Israel.

French Foreign Minister Jean-Noel Barrot will later Friday meet Iranian counterpart Abbas Araghchi in Geneva "to make a complete diplomatic and technical offer for negotiations," Macron told reporters, adding that France and allies Germany and the UK were "putting a diplomatic solution on the table".

Iran's supreme leader, Ayatollah Ali Khamenei, who crushed internal threats repeatedly during more than three decades in power, now faces his greatest challenge yet.

His archenemy, Israel, has secured free rein over Iran's skies and is decimating the country's military leadership and nuclear program with its punishing air campaign. It is also threatening his life: Israeli Defense Minister Israel Katz said Khamenei "cannot continue to exist."

Iran's foreign minister plans to meet in Geneva on Friday with leading European counterparts, who hope to open a window for a diplomatic solution to the weekold war that has seen Israeli airstrikes target Iranian nuclear and military sites and Tehran firing back.

Iranian Foreign Minister Abbas Araghchi, however, said his country is not seeking negotiations with anyone as long as Israel continues its strikes on Iran.
