'No justification' for Russian threat of nuclear weapons

The computer simulation was carried on State-owned Russia-1 TV at the weekend and showed the Poseidon torpedo being fired from a submarine, the Belgorod, and exploding some 300km north-west of Donegal.

The Department of Foreign Affairs has said there is no justification for the threatened use of nuclear weapons and reminded Russia that it said last January a nuclear war “must never be fought”.

The department was responding to reports on Russian state TV showing computer-simulated nuclear attacks on Britain, which also wipes out Ireland.
