The U.S.-Ukraine alliance is careening toward a possible breaking point, with Moscow strengthened by President Donald Trump's recent rejection of new Russia sanctions and Kyiv undermined by disruptions in satellite support for its drones during the war.

Trump's relationship with Ukrainian President Volodymyr Zelensky has always been a moving target, while the Republican president has frequently boasted of his rapport with Russian leader Vladimir Putin. But relations between the U.S. and Ukraine appear to be at a new low, threatening to tip the balance of the war to Russia's favor and imperil America's security interests across the globe.

U.S. envoy Steve Witkoff will travel to Oslo to take part in talks Tuesday with Ukraine President Volodymyr Zelensky and the leaders of Norway and Finland, while Jared Kushner will participate remotely, Norway's government said.

"Ukraine has requested that U.S. special envoys Steve Witkoff and Jared Kushner join the meetings. I am pleased that they are able to participate. Diplomatic efforts have previously taken place in several countries, and Norway and Finland are pleased to be able to continue this work. The aim is to put diplomatic efforts on a more constructive path," Norwegian Prime Minister Jonas Gahr Store said in a statement.

U.S. Secretary of State Marco Rubio was in Uzbekistan on Monday to promote trade and ties with Central Asia, during a trip that came amid rumblings that America's top diplomat is ignoring pressing matters in favor of politically safer visits and meetings.

The trip, which involves a stop in India later this week, seeks to promote U.S. economic and security ties with Central and South Asia. But it has only tangential links to the Trump administration's current main foreign policy dilemmas in the Middle East and with the Russia-Ukraine war.

French Prime Minister Sébastien Lecornu says he has instructed prefects to impose "very limited" and "localized" curfews in cities to prevent more rioting and looting, following this weekend's violence that notably targeted city halls, other public buildings and hundreds of businesses across the country.

Speaking after an emergency meeting with top government officials, Lecornu said "on Saturday, despite scenes of severe violence and extensive property damage, no one was killed, and that is a miracle" as he defended the work of police officers faced with violent groups of people.

Russia's foreign minister has arrived in Tehran for his first visit since the outbreak of the Middle East war, Russian news agencies reported on Monday, as Moscow seeks to play a mediating role.

Arriving from Bahrain, Sergei Lavrov was scheduled to meet with Iranian President Masoud Pezeshkian and Foreign Minister Abbas Araghchi.

Russia attacked Kyiv with ballistic missiles and drones overnight Monday, killing one person and injuring eight others as well as damaging buildings and infrastructure in three districts, local authorities said.

Ukraine's Air Force said Russia launched a large-scale overnight air attack with ballistic missiles, cruise missiles and 269 drones. Ukrainian air defenses destroyed or suppressed 243 drones and four missiles, the air force said.

France's Interior Minister Laurent Nunez admitted Monday that the police "lost control" in some cities during violent protests that erupted in cities across the country at the weekend.

He said there had been a "lack of anticipation" in preparations and that he had tendered his resignation to President Emmanuel Macron "because I felt responsible for everything that happened." Macron did not accept his resignation.

U.S. Vice President JD Vance — who participated in negotiations with Iran over the summer — has defended President Donald Trump's Iran strategy, and said the Trump administration is looking for a "final firm commitment from the Iranians that they're not going to rebuild their nuclear program."

France woke up Sunday to devastated streets after clashes between police and protesters, mass looting and fires erupted nationwide as marches against rising costs of living degenerated into "extreme" violence.

U.S. President Donald Trump has predicted that the ongoing war with Iran will end “very quickly,” promising that American gas prices will fall below pre-war levels once hostilities cease.
