A Russian drone and missile attack on Ukraine’s capital overnight killed at least four people and injured others, according to Ukraine’s emergency services, as rescue workers and firefighters sought to remove people they believed trapped under debris in a partially collapsed apartment building, Associated Press reported.

The strikes came nearly a week after a combined Russian attack on Ukraine last Tuesday killed 28 people in Kyiv, 23 of them in a residential building that collapsed after sustaining a direct hit by a missile. Ukrainian President Volodymyr Zelenskyy called that attack one of the biggest bombardments of the war, now in its fourth year.

In the early hours of Monday, drones and missiles hit residential areas, hospitals and sports infrastructure in numerous districts across Kyiv, emergency services said, with the most severe damage occurring in the Shevchenkivskyi district, where one section of a five-story apartment building collapsed, according to Associated Press.
