Ireland will pledge an additional €325,000 to the Council of Europe, the Taoiseach has announced at a Council summit in Reykjavik.
This funding will go towards the European Court of Human Rights and to those working with opposition groups in Belarus.
The Council has faced a funding shortfall after it decided last year that Russia could no longer be a member of the organisation, founded in 1949.
Leaders from the Council's 46 member states have been arriving in the Icelandic capital tonight for this just the fourth time it has met at summit level.
Icelandic Prime Minister Katrin Jakobsdotir said Council stands with Ukraine and commends its resistance in a war on European values.
She called on Russia to withdraw from Ukraine as "a first step" to ending the war.
The Reykjavik Summit was about reaffirming core values in a time of democratic backsliding, she said.
Ukrainian President Volodymyr Zelensky addressed the summit remotely tonight.
He said Russia had used ballistic and cruise missiles at the same time in its latest attack on Ukraine.
But he said "all lives were protected" and he thanked the European Leaders for their support.
"If we are able to do this, is there anything we can't do if we are united?" he asked the Council Leaders.
He called for fighter jets saying no air defence can be perfect without them.
The Ukrainian President said there must be a tribunal established to deal with Russian aggression and a full compensation structure put in place.
