A Russian strike on a weapons depot near Kyiv killed at least 37 people on Saturday, in one of the deadliest attacks this year. The depot, storing Ukrainian ammunition close to civilian buildings, caused massive secondary explosions. Ukrainian President Volodymyr Zelensky called the storage negligent and vowed a criminal investigation. Officials said a home for older adults and disabled people was among the severely damaged buildings. The capital region will observe a day of mourning on Sunday.

Serhii Koretskyi, Ukraine's prime minister, stated that making the same mistakes for the fifth year of the full-scale invasion is criminal negligence. All those responsible must face severe punishment. An ammunition facility outside Kyiv was destroyed last month, killing several people and prompting a separate investigation into storing dangerous arms in civilian areas.

Russia has launched a blitz of attacks targeting warehouses and shopping centers. Waves of drones, many powered by jet engines flying nearly 400 miles an hour, have surged into Kyiv, straining limited air defenses. Ukraine faces a dire shortage of Patriot interceptor missiles. Civilians brace for the possibility of larger ballistic attacks. Most shops remain open, but constant attacks have caused major traffic jams and metro delays, complicating plans for students to return to school.
