Moscow has been hit by a second drone attack in less than a week, with the same building targeted.
Russia’s Defence Ministry claimed its forces had “thwarted an a terrorist attack by the Kyiv regime" and downed two drones.
Ukrainian drone attacks on Russia have become more frequent since Putin’s forces invaded in March 2022. Kyiv has not commented on the latest incident.
“Yet another (drone) was hit by radio-electronic equipment and, having run out of control, crashed on the territory of the complex of non-residential buildings at Moskva Citi," the ministry said, referring to a business centre in the capital.
Earlier, Moscow Mayor Sergei Sobyanin said: “One flew into the same tower at the Moskva City complex hit previously. The facade has been damaged on the 21st floor. Glazing was destroyed over 150 square metres."
No injuries were reported. It represents an embarrassment for Vladimir Putin, as the Kremlin has vowed tighter security in the wake of previous drone attacks.
Another drone targeted a district police department early Monday in Russia’s Bryansk region, which borders Ukraine, but there were no casualties.
It comes as Russian ballistic missiles hit an apartment complex and a university building in the central Ukrainian city of Kryvyi Rih on Monday, killing five people and wounding 64.
The blasts trapped residents beneath rubble, Ukrainian officials said.
One of the two missiles destroyed a section of the apartment building between the fourth and ninth floors, Interior Minister Ihor Klymenko said.
Video showed black smoke billowing from corner units and burned out or damaged cars on a tree-lined street.
The dead included a 10-year-old girl and her mother, according to Ukrainian President Volodymyr Zelensky, who comes from Kryvyi Rih.
More than 350 people were involved in the rescue operation, he said in a Telegram post.
The morning attack also destroyed part of the four-story university building.
