KYIV, Ukraine: Ukraine was on Tuesday marking the fourth anniversary of Russia’s full-scale invasion, with a show of solidarity from its staunchest allies and no immediate end in sight to Europe’s bloodiest conflict since World War II.

Tens of thousands of lives have been lost since the Kremlin ordered troops into Ukraine on February 24, 2022, confident of a quick victory but not expecting the fierce resistance that followed.

The worldwide fallout of the war has been immense, with many European countries increasing their own defense spending in anticipation of a possible confrontation of their own with Russia.

But diplomatic talks between the two sides, relaunched last year by the United States, have so far failed to halt the fighting, which has devastated Ukraine and left it facing the mammoth task — and bill — of reconstruction.

Tuesday’s anniversary is expected to see the head of the European Commission, Ursula von der Leyen, and the president of the European Council, Antonio Costa, in Kyiv to mark the occasion.
