President Recep Tayyip Erdogan on Tuesday said Turkey would be the "ideal host" for any talks to end the nearly three-year conflict between Russia and Ukraine.

Ukrainian President Volodymyr Zelensky said Tuesday that any talks aimed at ending the war should be "fair" and involve European countries, including Turkey.

The top diplomats from Russia and the U.S. met Tuesday in Saudi Arabia to discuss improving ties and negotiating an end to the war in Ukraine — talks that represented a rapid and major change in American foreign policy under President Donald Trump.

No Ukrainian officials were present at the meeting, which came as the beleaguered country is slowly but steadily losing ground against more numerous Russian troops in a grinding war that began nearly three years ago. President Volodymyr Zelenskyy said his country won't accept any outcome from this week's talks if Kyiv doesn't take part. European allies have also expressed concerns they are being sidelined.

Russia has freed a U.S. citizen arrested earlier this month on drug smuggling charges, according to Russian media reports and a U.S. official.

The move appears to be an effort to ease tensions between Moscow and Washington ahead of talks in Saudi Arabia on Tuesday.

When Hamas threatened to call off the planned release of three Israeli hostages last week, U.S. President Donald Trump stepped into the picture with an unexpected ultimatum.

Speaking in the Oval Office, Trump called on Hamas to release all of the more than 70 hostages it is holding by noon on Saturday. Otherwise, he warned, "all hell is going to break loose."

Ukrainian President Volodymyr Zelensky says he directed his ministers not to sign off on a proposed agreement to give the United States access to Ukraine's rare earth minerals because the document was too focused on U.S. interests.

The proposal, which was a key part of Zelensky's talks with U.S. Vice President JD Vance on the sidelines of the Munich Security Conference on Friday, did not offer any specific security guarantees in return, according to one current and one former senior Ukrainian official familiar with the talks.

French President Emmanuel Macron called leaders from key European Union nations and the United Kingdom to his ornate Elysee Palace on Monday for an emergency meeting on how to react to the U.S. diplomatic blitz on Ukraine, which left the once rock-solid partner as a potential political liability.

The first visit by top U.S. officials to Europe has left the impression that the Trump administration was ready to embrace the Kremlin while it cold-shouldered many of its age-old European allies.

Ukrainian President Volodymyr Zelensky traveled to the United Arab Emirates late Sunday as momentum grows for potential peace talks ending Moscow's war on the country.

U.S. President Donald Trump last week suggested he would be meeting Russian President Vladimir Putin in Saudi Arabia. The UAE, home to Abu Dhabi and Dubai, long has been floated as a possible site for peace talks as well given the large population of Russian and Ukrainian expatriates who have flooded the country since the war began, and due to the Emirates' work on prisoner exchanges in the past.

Top Russian officials will hold talks with U.S. counterparts on restoring ties, negotiating a peaceful settlement to the war in Ukraine and preparing a meeting between Russian President Vladimir Putin and U.S. President Donald Trump, the Kremlin said Monday.

Kremlin spokesman Dmitry Peskov said that Russian Foreign Minister Sergey Lavrov and Putin's foreign affairs adviser Yuri Ushakov will fly to the Saudi capital later in the day to take part in the talks set for Tuesday.

A senior team from U.S. President Donald Trump's administration will start talks in Saudi Arabia with Russian and Ukrainian negotiators on ending the Ukraine war, U.S. officials said.
