The energy war between Russia and Ukraine has entered a new phase of more systematic aerial attack on Ukraine's grid and Russia's oil infrastructure.

Four years to the day since Russia’s full-scale invasion of Ukraine began, the EU hoped to bring some comfort in the form of fresh sanctions against Moscow and a €90 billion loan to Kyiv. Hungary has stopped that happening.

Ukrainians paused in silence across the country on Tuesday (February 24) as soldiers lowered military flags in the Ukrainian capital of Kyiv to mark another year of Russia’s full-scale invasion.

More than a dozen senior European officials are visiting Kyiv in a show of support. But only one American is listed among the official guests.
