Discussions between foreign ministers from Nato countries are getting under way in Brussels.
Opening the session of talks, Nato secretary general Jens Stoltenberg said the talks would cover support for the "brave Ukrainians defending their country" and "further support to other partners at risk from Russian aggression".
He said the Russian invasion, launched six weeks ago, had "profoundly changed the security environment in Europe" and the meeting would also discuss "longer-term adaptation".
Ukraine's Foreign Minister, Dmytro Kuleba, is also at the Nato gathering, and earlier said he wanted to discuss one thing: "Weapons, weapons, weapons."
