Ukraine conflict: Russia blames Liz Truss and others for nuclear alert

Vladimir Putin put Russia's nuclear forces on high alert after comments by UK Foreign Secretary Liz Truss and others, the Kremlin has said.

Kremlin spokesman Dmitry Peskov said "unacceptable" remarks were made about possible "clashes" between Nato and Moscow over Russia's attack on Ukraine.

It is unclear precisely which comments by Ms Truss Russia objects to.

On Sunday, she said if Russia was not stopped, other states may be threatened and it could end in conflict with Nato.

A Foreign and Commonwealth Office source told the BBC: "I don't think anything Liz has said warrants that sort of rhetoric or escalation."

They said the foreign secretary had always spoken about Nato as a "defensive alliance" and that the UK needed to support Ukraine.

Echoing comments by Defence Secretary Ben Wallace earlier, the source insisted the UK wanted to avoid "any sort of miscalculation".
