'Peace on our continent has been shattered': Nato chief on the Russian invasion of Ukraine – video

Nato has increased its troop presence on its eastern boundary in response to Russia's invasion of Ukraine, secretary general Jens Stoltenberg has said.

'This is a deliberate, cold-blooded and long-planned invasion,' Stoltenberg said. 'Russia's unjustified, unprovoked attack on Ukraine is putting countless innocent lives at risk with air and missile attacks.'

He said Nato had activated its defence plans, allowing freer movement of troops, but would respond in a defensive rather than combative manner
