EU foreign ministers meet in Luxembourg after Russian attack kills at least 34 in Sumy

Even by the warped standards of wartime, Russia’s Sunday morning attack on Sumy was astonishingly brazen. Two high-speed ballistic missiles, armed, Ukraine says, with cluster munitions, slammed into the heart of the border city in mid-morning as families went to church, waited for a theatre performance or were simply strolling about on a mild spring day.

To contemplate a daytime city-centre attack, in the full knowledge that civilians will be present, reflects a Russian culture of impunity that has been allowed to endure without effective challenge. Nevertheless, Washington’s approach, under Donald Trump, has been to try to negotiate an end to the war by talking directly with Moscow, while remaining mostly silent on Russian attacks on civilians.
