Three coffins — one adult-sized, one medium and one child-sized — lay Wednesday inside the Soviet-era Palace of Culture in this northern Ukrainian city, surrounded by dozens of bouquets as a church choir sang farewell prayers. The funeral was for 8-year-old Tamara, 12-year-old Stanislav, and 17-year-old Roman Martyniuk — siblings from the same family. The children's deaths underscore the mounting toll on Ukrainian families as Moscow ramps up its strikes amid faltering peace efforts.
