The Taoiseach has called on Russia to stop the "needless killing of young people" and declare a ceasefire in Ukraine.

Micheál Martin has described a speech delivered by Russian president Vladimir Putin, in which he indicated he was willing to use nuclear weapons against Ukraine, as "grave" and "concerning".
