European leaders on Monday condemned the attack as a war crime. There were calls for more sanctions on Russia. A Kremlin spokesman says Russia’s military only strikes military targets.

BRUSSELS (AP) — Russia on Monday claimed its deadly missile attack on Ukraine’s Sumy that killed and wounded scores including children had targeted a gathering of Ukrainian troops, while European leaders condemned the attack as a war crime.

Ukrainian officials have said two ballistic missiles on Palm Sunday morning hit the heart of Sumy, a city about 30 kilometers (less than 20 miles) from Ukraine’s border with Russia, killing at least 34, including two children, and wounding 119. It was the second large-scale attack to claim civilian lives in Ukraine in just over a week.
