The organizations unifying the European federalists including Lithuanian federalists expressed the support for the Euromaidan participants and condemned the Ukraine's Government for the use of the force against the peaceful protesters.
An open letter initiated by deputy speaker of the Seimas Petras Austrevicius was signed by the 29 organization from 19 European countries.
The initiative was also supported by German Member of the European Parliament and the current Chairman of the European Parliament Committee on Foreign Affairs Elmar Brok who is currently visiting Ukraine.
"Millions of Ukrainians who are not scared of the perishing winter's cold and who have gathered to express the support for the European Ukraine's future are inspiring all citizens of Europe," the letter states.
Six people have died since protests began in Ukraine two months ago. They include three protesters and hee police men. Demonstrators have taken to the streets following President Yanukovych's refusal to sign an association agreement with the European Union last year.
Ukrainian Prime Minister Mykola Azarov and his entire cabinet resigned earlier this week amid the unrest. Baltic leaders, meanwhile, have called for the situation to be resolved via dialog.
