A Russian drone attack on a shopping mall in the south-central Ukrainian city of Kryviy Rih on August 21 killed at least 16 people and left more than 130 others injured, including 23 children, some of them in critical condition.A day later, nine people were still unaccounted for. The fire engulfed over 9,000 square meters and took hours to extinguish.Two Russian jet-powered drones struck the largest shopping mall in the city early afternoon on August 21. The attack came as many residents were out shopping at the end of the work week."There was smoke. Everyone was shouting," Yuliana, a mall employee, told RFE/RL's Ukrainian Service.She said the attack caused parts of the ceiling to collapse in a parking garage where some shoppers and staff had sought shelter during an air-raid alert, and that a car was blocking the entrance, forcing people to climb over metal barriers.Ukrainian Foreign Minister Andriy Sybiha said Russia deliberately struck the site twice, and that the second wave of drones came after emergency responders arrived at the scene."Such barbaric double-tap strikes are intended to maximize civilian casualties. They prove Russia's status as a terrorist state," he wrote calling for “criminals responsible for such atrocities” to be brought to account.Air defense failed to detect the drones because they flew at an "exceptionally low altitude," according to Oleksandr Vilkul, head of the city's defense council.President Volodymyr Zelenskyy, a native of Kryviy Rih, reiterated his call for air defense support -- new supplies of ballistic and other missile interceptors -- from international partners."Every day that Ukraine lacks air defense is a sacrifice that could have been avoided," he wrote on August 22.
