A Russian missile strike hit a crowded shopping centre in the central Ukrainian city of Kremenchuk on Monday, killing at least two people and wounding 20, senior Ukrainian officials said.
The attack caused a huge fire and sent dark smoke billowing into the sky, footage circulated by President Volodymyr Zelenskiy showed.A Reuters reporter saw the charred husk of a shopping complex with a caved-in roof. Firefighters and soldiers were pulling out mangled pieces of metal as they searched for survivors.
"It's useless to hope for decency and humanity from Russia," Zelenskiy wrote on the Telegram messaging app.
"Rescuers from all surrounding areas are heading to the scene to put out the fire and work to liquidate the consequences," Tymoshenko said.
"We need more weapons to protect our people, we need missile defences," Andriy Yermak, head of the president's office, said.
Vadym Denysenko, an interior ministry adviser, said Russia could have had three motives for the attack.
"The first, undoubtedly, is to sow panic, the second is to... destroy our infrastructure, and the third is to... raise the stakes to get the civilised west to sit down again at the table for talks," he said.
Russia, which captured Ukraine's eastern frontline city of Sievierodonetsk over the weekend after a weeks-long assault, has stepped up missile strikes on targets across Ukraine in recent days.Missiles slammed into an apartment block and landed close to a kindergarten in the Ukrainian capital on Sunday, killing one person and wounding several more people.
