Ukrainian President Volodymyr Zelensky and Kiev did not take responsibility for the attack, which Reuters said showed the conflict was “gradually returning to Russian territory – its symbolic heartland.”

Tech company Yandex has ordered its employees to evacuate its offices at night due to its proximity to the Russian capital and the high risk of a strike, the media said.

“Given the circumstances, we kindly ask that you not be in the office overnight (between 1am and 6am),” Yandex reportedly told staff. “This restriction applies to all offices in Moscow. Watch out!”

The growing attacks are starting to surprise other Russian civilians.

“I would say that it has increased anxiety for myself as well as for me and my colleagues,” reportedly said an anonymous person who works in the financial district. “Somewhere in my heart, I always knew that City could be one of the targets.”

“I don’t think anyone is safe now,” said another employee of the Russian company.
