Two Russian missiles slammed into a crowded shopping centre in the central Ukrainian city of Kremenchuk on Monday, killing at least 11 people and wounding 50, the regional governor said.

President Volodymyr Zelensky said more than 1,000 people were in the shopping centre at the time of the attack, which witnesses said caused a huge fire and sent dark smoke billowing into the sky.

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 is impossible to even imagine the number of victims ... It`s useless to hope for decency and humanity from Russia," Zelensky wrote on the Telegram messaging app.

Dmytro Lunin, governor of the central Poltava region, wrote on Telegram that 11 people had now been confirmed killed by the strike, adding that rescue workers would keep searching through the smouldering rubble, with more bodies likely to be found.

Lunin also wrote on Telegram that 21 people had been hospitalised, and 29 others had been given first aid without hospitalisation.

"It`s an act of terrorism against civilians," he said separately, suggesting there was no military target nearby that Russia could have been aiming at.

At one point, paramedics rushed into the building after rescuers called out "200" meaning they had found one or more bodies in the building. Reporters were later pushed away from the scene as air raid sirens wailed again.

UKRAINE WANTS MORE WEAPONS

As night began to fall, rescuers brought lights and generators to continue the search. Worried family members, some close to tears and with hands over their mouths, lined up at a hotel across the street from the mall where rescue workers had set up a base.

Kiril Zhebolovsky, 24, was looking for his friend, Ruslan, 22, who worked at the Comfy electronics store and hadn’t been heard from since the blast. “We sent him messages, called, but nothing,” he said. He left his name and phone number with the rescue workers in case his friend is found.

Kremenchuk, an industrial city of 217,000 before Russia`s Feb 24 invasion of Ukraine, lies on the Dnipro River in the region of Poltava and is the site of Ukraine`s biggest oil refinery.

Ukraine`s air force command said the mall was hit by two long-range X-22 missiles fired from Tu-22M3 bombers that flew from Shaykovka airfield in Russia`s Kaluga region.

Russia did not immediately comment on the Ukrainian assertion. It has denied deliberately targeting civilians during in its "special military operation" in Ukraine.

"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 has captured the eastern Ukrainian city of Sievierodonetsk after a weeks-long assault, has stepped up missile strikes across Ukraine in recent days. Read full story
