“I'm confident with combined efforts we can bring all of those responsible to justice, and I promise you we'll find them all,” the Ukrainian president added.

Michel and Zelensky spoke for two hours, discussing sanctions, weapons, Ukraine’s membership to the European Union and financial support, things that Ukraine “really needs,” Zelensky said.

Membership to the EU is a “priority” for Ukraine, and the country is “hoping and waiting” for the support from EU member states, Zelensky said.
