Russian strikes on a crowded DIY hardware store and a residential area in the Ukrainian city of Kharkiv killed at least six people and injured 40 on Saturday, local officials said. Four people were killed after two guided bombs hit the DIY hypermarket in a residential area of the city, regional governor Oleh Syniehubov said on national television, while 40 people were injured in the attack and 16 still unaccounted for. At least two of the dead were store employees. Kharkiv mayor Ihor Terekhov said about 120 people had been in the hardware store when the bombs struck. “The attack targeted the shopping centre, where there were many people – this is clearly terrorism,” Terekhov said. An early evening missile strike hit a residential building in the centre of the city of 1.3 million, injuring 18 people, Syniehubov said. The missile left a crater several metres deep in the pavement at the foot of the building, which also housed a post office, a beauty salon and a cafe. Emergency workers ushered away residents of nearby apartment buildings. Some of the injured had blood on their faces. Kharkiv, Ukraine’s second-largest city, is just 30km (18 miles) from the Russian border and has been the target of Russian attacks for weeks. This month, Russian troops also staged an incursion into northern areas of Kharkiv region. Andriy Kudinov, director of the suburban shopping centre, told local media the hardware store was full of shoppers buying items for their summer cottages. Huge clouds of dark smoke billowed over the shopping centre. Firefighters battled many small blazes. Within 90 minutes, most were brought under control. Rescuers, medics and journalists rushed away from the scene of both strikes and lay on their stomachs, fearing a second strike – a common feature of Russia’s recent attacks. Witnesses described panicked scenes at the shopping centre. “I was at my workplace. I heard the first hit and … with my colleague, we fell to the ground. There was the second hit and we were covered with debris. Then we started to crawl to the higher ground,” said Dmytro Syrotenko, 26, who had a large cut on his face. Syrotenko told Reuters he was taken to safety by a rescue worker who helped him, several colleagues and shoppers. Volodymyr Zelenskiy, in his nightly video address, denounced the strike as “yet another example of Russian madness. There is no other way to describe it”. “When we tell world leaders that Ukraine needs sufficient air defences, when we say we need real decisive measures to enable us to protect our people so that Russian terrorists cannot even approach our border, we are talking about not allowing strikes like this to happen,” he said. Moscow denies deliberately targeting civilians, but thousands have been killed and injured during its 27-month full-scale invasion of Ukraine.
