It has been one month since Russia launched its invasion of Ukraine on 24 February.
Fighting has forced more than millions of Ukrainians to flee their homes and more than 3.5 million to flee the country, with thousands of people killed or wounded and widespread damage in the wake of shelling and aerial bombardments.

The State Department called Wednesday’s move “Russia’s latest unhelpful and unproductive step” in relations between the countries. It urged Russia “to end its unjustified expulsions of US diplomats and staff.”
