Nato and Kyiv will hold emergency talks on Tuesday over Russia’s use of an experimental, hypersonic ballistic missile. The Kremlin fired the new intermediate-range ballistic missile at a central Ukrainian city on Thursday in response to Kyiv’s use of American and British missiles capable of striking deeper into Russia.

In a stark warning to the West, President Putin said the attack with the intermediate-range Oreshnik missile was in retaliation for Kyiv’s use of U.S. and British longer-range missiles.

WASHINGTON (Reuters) - President-elect Donald Trump chose lawyer Matthew Whitaker on Wednesday to be U.S. ambassador to NATO, selecting a loyalist with little foreign policy experience for what may be one of the highest-profile ambassadorships during Trump's second administration.

The choice of Whitaker as the nation's representative to NATO is an unusual one, given his background is in law enforcement and not in foreign policy.

President-elect Donald Trump, who has long criticized NATO as overly reliant on American money, on Wednesday nominated loyalist Matthew Whitaker to the crucial post of ambassador to the alliance.
