KREMENCHUK, Ukraine, June 27 (Reuters) - Russian missiles struck a crowded shopping mall in central Ukraine on Monday, President Volodymyr Zelenskiy said, as Moscow fought for control of a key eastern city and Western leaders promised to support Kyiv in the war "as long as it takes".

More than 1,000 people were inside when two Russian missiles slammed into the mall in the city of Kremenchuk, southeast of Kyiv, Zelenskiy wrote on Telegram. At least 16 people were killed and 59 injured, Ukraine's emergency services said. Rescuers trawled through mangled metal and debris for survivors.

"This is not an accidental hit, this is a calculated Russian strike exactly onto this shopping centre," Ukrainian President Volodymyr Zelenskiy said in an evening video address, adding there were women and children inside. He said the death count could rise.

Russia has not commented on the strike, which was condemned by the United Nations and Ukraine's Western allies. But its deputy ambassador to the United Nations, Dmitry Polyanskiy, accused Ukraine of using the incident to gain sympathy ahead of a June 28-30 summit of the NATO military alliance.

"One should wait for what our Ministry of Defence will say, but there are too many striking discrepancies already," Polyanskiy wrote on Twitter.

As night fell in Kremenchuk, firefighters and soldiers brought lights and generators to continue the search. Family members, some close to tears and with hands over their mouths, lined up at a hotel across the street 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 had not 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.

The United Nations Security Council will meet Tuesday at Ukraine's request following the attack on the shopping mall. U.N. spokesman Stephane Dujarric said the attack was "deplorable".

Leaders of the Group of Seven major democracies, gathered for their annual summit in Germany, condemned what they called an "abominable" attack.
