A gunman killed at least 18 children and three adults at an elementary school in Texas, according to local officials. Greg Abbott, Texas’s governor, said the suspected murderer, an 18-year-old man, was killed by police. The massacre in Uvalde, Texas, comes on the heels of mass shootings in Buffalo, New York, and southern California earlier this month. Active-shooter incidents surged by more than 50% between 2020 and 2021, and by nearly 97% since 2017, according to new data released Monday by the Federal Bureau of Investigation.

Russia redoubled its efforts to take the parts of Donbas still under Ukrainian control by trying to encircle the cities of Sievierodonetsk and Lysychansk, in Luhansk. A poll found that 82% of Ukranians oppose the idea of offering any territorial concessions during peace talks. Meanwhile the underground railway in Kharkiv reopened after being used as a bomb shelter since Russia invaded, three months ago on Tuesday.
