Live updates: At least 4 killed overnight in Kyiv shelling

KYIV, Ukraine — Shelling in a Kyiv neighborhood has devastated a shopping center, leaving a flattened ruin still smoldering Monday morning in the midst of high-rise towers.

Emergency services reported at least four people were killed by the overnight shelling near the city center late Sunday. The force of the explosion shattered every window in the high-rise next door and twisted their metal frames.

In the distance, the sound of artillery rang out as firefighters picked their way through the destruction in the densely populated Podil district.

OTHER DEVELOPMENTS TODAY:

LVIV, Ukraine — An ammonia leak at a chemical plant in the eastern Ukrainian city of Sumy has contaminated an area with a radius of more than 2.5 kilometers (about 1.5 miles), officials said early Monday.

Sumy regional governor Dmytro Zhyvytskyy didn’t say what caused the leak.

The Sumykhimprom plant is on the eastern outskirts of the city, which has a population of about 263,000 and has been regularly shelled by Russian troops in recent weeks.

“For the center of Sumy, there is no threat now, since the wind does not blow on the city,” said Zhyvytskyy.

He said the nearby village of Novoselytsya, about 1.5 kilometers (1 mile) southeast of Sumy, is under threat.

Emergency crews were working to contain the leak.
