Two children were among the scores of people killed in the Palm Sunday strikes on the city’s center, while 117 people were wounded, according to Ukraine’s State Emergency Service.

European officials condemned Monday Russia's deadly missile attack on Ukraine's Sumy that killed and wounded scores, accusing Moscow of committing war crimes and demonstrating disregard for Washington-led efforts to end the war.

The missile strike Sunday was one of the deadliest single attacks on Ukraine this year, as diplomatic efforts led by the U.S. have yielded few results.
