European Union leaders will meet for an extraordinary summit on March 6 to discuss additional support for Ukraine, European security guarantees and how to pay for European defence needs, EU officials said on Sunday.

The leaders of the 27 European Union countries will hold an emergency summit on March 6 about next steps for Ukraine and Europe’s security.

European leaders have been shaken by Trump’s overtures to Russia to end the three-year-old invasion and improve relations between the two powers. Many fear a deal to end the war could be made without European or Ukrainian involvement.

Estonia has launched a new push to get fellow EU members to agree to seize frozen Russian assets and use them to help Ukraine, dismissing a Russian idea on how the money could be used as part of a peace deal.

The European Union is discussing how to seize Russia’s frozen central bank assets to provide financial and military aid to Ukraine, as concerns grow that the United States may scale back its support.
