Are we about to see a further escalation in the Ukraine war?

It's now more than 1,000 days after Russia's invasion of Ukraine, and there are signs that the conflict is taking on a new dimension. The use of Western-supplied long-range missiles by Ukraine on targets within Russia led to renewed sabre-rattling from Vladimir Putin, sparking questions over whether Moscow could consider using nuclear weapons.

To examine all this, Laura Byrne is joined by Donnacha Ó Beacháin, professor of politics at Dublin City University.
