Ukrainian President Volodymyr Zelenskyy was due to hold urgent talks Thursday with leaders and officials from about 30 countries that are supporting Kyiv’s effort to obtain fair terms for an end to the war with Russia.

World leaders are preparing for a new round of discussions on the Ukraine war as tensions and uncertainty grow. President Volodymyr Zelenskyy hinted at major developments ahead, while former United States President Donald Trump voiced caution over renewed European talks.

Zelenskyy is referring to the 20-point peace settlement proposal that Ukraine, the United States and European leaders have been working on for weeks. Ukraine expects to “deliver this document to the United States in the near future,” following work with the US negotiating team and European leaders, Zelenskyy added.

Russia launched a huge attack on Ukraine overnight as the country marked Armed Forces Day on Saturday, Ukraine's air force said.

Ukraine’s leader said Wednesday he anticipates handing over a revised peace proposal to the US “in the near future.”

Zelenskyy and his European allies have repeatedly accused Russian President Vladimir Putin of slow-walking the talks to press ahead with the invasion as his forces are making slow buy steady gains while waves of missiles and drones are pummeling Ukrainian infrastructure.

KYIV, Ukraine -- KYIV, Ukraine (AP) — President Donald Trump on Sunday claimed Ukrainian President Volodymyr Zelenskyy “hasn’t read” a U.S-authored peace proposal aimed at ending the Russia-Ukraine war.

Foreign policy analyst Matt Duss discusses the status of Russia-Ukraine ceasefire talks and new data on the extent of casualties from the now nearly four-year Russian invasion of Ukraine. Hundreds of thousands of people have been killed.

The issue is that “nobody believes” giving Russia Ukrainian territory is a “true alternative” to create lasting peace, Bosak says.

NATO fighter jets were scrambled and air defense systems put on alert in Poland in response to Russia’s latest overnight drone and missile strikes in Ukraine.
