European leaders are expected to cement support for Ukraine as it faces Washington’s pressure to swiftly accept a U.S.-brokered peace deal.

Ukrainian President Volodymyr Zelenskiy resumed talks with U.S. President Donald Trump's envoys in Berlin on Monday, after the U.S. side said a lot of progress had been made on ending Europe's deadliest conflict since World War Two.

A 1,000-strong "dark fleet" of rogue tankers evading sanctions has become a new target for the U.S. and Ukraine, according to a senior maritime intelligence analyst.

Ukrainian President Volodymyr Zelenskyy said in a social media post on Sunday morning that "hundreds of thousands" of Ukrainians were without electricity across multiple regions following Russian missile and drone attacks on the country's energy infrastructure.

The European Union’s effort to tap Russian assets as the main source of international funding for Ukraine is becoming “increasingly difficult” as leaders struggle to agree on a framework, the bloc’s top foreign policy official said.

The latest overnight attacks come as US envoy Steve Witkoff prepares to hold more talks with Ukraine's president.

The president said he had exchanged “pretty strong words” with European leaders, while Russia signaled it saw itself as increasingly on the same page as the U.S.

Ukrainian President Volodymyr Zelensky said this week his country could be ready to hold elections in the next 60 to 90 days if security could be guaranteed, seeking to push back on claims by US President Donald Trump that he is using the war with Russia to cling to power.

After almost four years of Russia's full-scale war, Kyiv is running out of cash, and needs an estimated €135.7bn over the next two years.
