The United States, together with the Group of Seven nations and the European Union, will move on Friday to revoke Russia's "most favored nation" status over its invasion of Ukraine, multiple people familiar with the situation said.

Russia's invasion of Ukraine is the biggest assault on a European country since World War Two. Moscow calls its actions in Ukraine a "special operation" to disarm Ukraine and unseat leaders it calls neo-Nazis. Ukraine and Western allies call this a baseless pretext for a war of choice that has raised fears of wider conflict in Europe.
Removing Russia's status of "Permanent Normal Trade Relations" with the United States would significantly escalate pressure on Russian President Vladimir Putin to end the largest conflict in Europe since World War Two.

The United Nations Security Council will convene on Friday at Russia's request, diplomats said, to discuss Moscow's allegations, which Washington has described as disinformation.
The information war picked up on social media as well, with Russia demanding that Washington stop the "extremist activities" of Facebook owner Meta Platforms, which temporarily lifted a ban on calls for violence against the Russian military and leadership.

Officials in Mariupol said Russian warplanes again bombed the city on Thursday, a day after a maternity hospital was pulverized in an attack the United States said was evidence of a war crime.

Lavrov said the hospital struck on Wednesday had stopped treating patients and had been occupied by Ukrainian "radicals". Russia's Defense Ministry later denied having bombed the hospital at all, accusing Ukraine of a "staged provocation".
