Russia to boost nuclear arsenal with 40 missiles

Vladimir Putin has said Russia will put more than 40 new intercontinental ballistic missiles into service this year, capable of overcoming even the most advanced defences.

He was speaking at a military fair showcasing a multi-billion dollar modernisation programme for the armed forces.

Mr Putin insists the West has nothing to fear but Nato accused him of nuclear sabre rattling and he's already accused of sending military hardware and troops to support rebels fighters in eastern Ukraine
