Russia-Ukraine War and Putin News: Live Updates

The existence of the message was disclosed as the Kremlin was funneling armaments, including attack helicopters, to Russia’s border with eastern Ukraine for the next phase of its two-month-old invasion of the country.

Over the course of the war, the U.S. administration has provided increasingly heavier weapons to the Ukrainians — including 155-mm howitzers — as the conflict has ramped up, and it announced a new $800 million arms package this week.

Back in February, as the war began, the administration worried such weaponry could unnecessarily provoke Russia. But after coming under pressure from President Volodymyr Zelensky of Ukraine and members of Congress from both parties, the administration has decided to provide some of the kinds of heavy weapons it says Ukraine will require in the next phase of the war.

The Russian warnings have come as the invasion has met unexpectedly stiff Ukrainian resistance and has exposed weaknesses in Russia’s conventional armed forces.

President Vladimir V. Putin of Russia has installed a new command to oversee the Ukraine war and this past week publicly suggested for the first time that Russia’s goals were limited to securing the Donbas, the section of eastern Ukraine bordering Russia where Moscow-backed separatists have been fighting for eight years.

Russia’s goals when its military invaded on Feb. 24 appeared far more ambitious, with plans to besiege and capture the capital, Kyiv, in the north, cutting off Mr. Zelensky’s government from the rest of the former Soviet republic, which Mr. Putin has said he does not even consider a country.

That strategy backfired and Russian forces retreated last month. They also have failed to completely seize the strategic southeast port of Mariupol despite relentless bombardments that have turned that once bustling city of 450,000 into a wasteland of death and war’s destructive horrors.

Pavlo Kyrylenko, the governor of the Donetsk region of Eastern Ukraine, told CNN on Friday that Ukrainian troops were still in control of Mariupol, but that the city had been “wiped off the face of the earth by the Russian Federation, by those who will never be able to restore it.”

In what appeared to be another military embarrassment for Russia that it has sought to cover up, a senior U.S. defense official said Friday that Russia’s Black Sea flagship Moskva, a missile cruiser that sank Thursday, had been struck by two Ukrainian Neptune missiles, and not crippled by an accidental fire and explosion during a storm, as the Kremlin has asserted.

It was the first American corroboration of Ukraine’s claims…
