A missile attack hit a shopping mall in the central Ukrainian city of Kremenchuk on Monday, killing 20 and injuring at least 59, the country's Ukrinform news agency reported Tuesday, citing Kyrylo Tymoshenko, deputy head of the Ukrainian president's office.

He said the search continues for more people. 

Ukraine on Monday accused Russia of targeting the shopping mall with more than 1,000 people inside.

But Russia's defense ministry on Tuesday denied the missiles strike on the shopping mall, saying it had struck a weapons depot and a subsequent explosion of ammunition had triggered a fire in the nearby mall.
