WASHINGTON (AP) Russian forces in Ukraine seem to have shifted their focus from a ground offensive aimed at Kyiv, the capital, to instead prioritizing what Moscow calls liberation of the contested Donbas region in the countrys industrial east, officials said Friday, suggesting a new phase of the war .

It appears too early to know where this will lead. Has President Vladimir Putin scaled back his ambitions in search of a way out of the war? The dug-in defensive positions taken recently by some Russian forces near Kyiv indicate a recognition of the surprisingly stout Ukrainian resistance.

On the other hand, Russian forces might be aiming to continue the war with a narrower focus, not necessarily as an endgame but as a way of regrouping from early failures and using the Donbas as a new starting point, one U.S. analyst said.

Putins forces are under great strain in many parts of the country, and the United States and other countries are accelerating their transfer of arms and supplies to Ukraine. In recent days, U.S. officials have said they see evidence of Ukrainian defenders going on the offensive in a limited way in some areas. Earlier this week they managed to attack a large Russian ship in port on the Black Sea coast.

Putting a positive face on it all, the deputy chief of the Russian general staff said his forces had largely achieved the main objectives of the first phase of what Moscow calls a special military operation in Ukraine. Col. Gen. Sergei Rudskoi said Russian forces had considerably reduced the combat power of the Ukrainian military, and as a result Russian troops could focus on the main efforts to achieve the main goal, liberation of Donbas.
