A 12-story residential building is struck in Kyiv, forcing evacuations.

Rescue operations were underway on Wednesday at a 12-story apartment building in Kyiv that was hit by Russian shelling, according to the Ukrainian emergency services.

People inside the city, which is under a 35-hour curfew imposed by the mayor on Tuesday amid intensifying Russian barrages, described explosions echoing in the night. Air raid sirens also sounded throughout the night.

Shortly after 6 a.m., rescuers received a report of a partly collapsed residential building in the city’s Shevchenkivskyi district, the State Emergency Service of Ukraine said on Facebook, and began evacuating people from the building. Two were injured, and at least 37 people were evacuated.

The area of the city is home to a cluster of universities, and before the invasion was known for lively student bars and restaurants.
