Ukrainian President Volodymyr Zelenskyj urgently called for more military support for his country in a video link at a summit meeting of EU heads of state and government. "It's important to prove this now," he said.

Ukraine has long been asking the EU for long-range weapons to destroy Russian attackers' supply lines far behind the front lines. There are fears that Russian President Vladimir Putin could also attack other NATO members such as Estonia or Lithuania if he wins over Ukraine. Germany is Ukraine's largest supporter in the EU with weapons delivered or already promised worth 28 billion euros.
