Additional Sanctions
The European Union says its new sanctions on Russia will have "maximum impact" on its economy and "political elite".
They were announced after a lengthy meeting of the European Council in Brussels last night, which was attended by Taoiseach Micheál Martin.

Not all possibilities for sanctions have been exhausted yet. The pressure on Russia must increase. Said this to @Vonderleyen. I am grateful to the President for her decision on additional financial assistance.
