Ukraine crisis: US rejects Russian demand to bar Ukraine from Nato

The US has rejected Russia's demand to bar Ukraine from Nato, amid warnings Russia might invade its neighbour.

Secretary of State Antony Blinken was giving Russia a formal response to its demands to resolve the Ukraine crisis.

Mr Blinken gave no concessions but said that he was offering Russia "a serious diplomatic path forward, should Russia choose it".

A Russian minister said his country would study Mr Blinken's response, delivered in coordination with Nato.
