Russia launched a massive air attack on the capital Kyiv and other Ukrainian cities on Thursday, injuring at least 18 people and damaging infrastructure facilities across the country, officials said.

Blasts were heard in Kyiv and the surrounding region after an air raid alert, Reuters witnesses said. Authorities reported sending rescue teams to several locations in the capital.

Interior Minister Ihor Klymenko said people were injured in Kyiv and Cherkasy regions and in the city of Kharkiv in the east during the attack that came early in the morning.

"It is a restless morning. Explosions were heard in different regions of Ukraine," he wrote on the Telegram messaging app.

Kyiv mayor Vitali Klitschko said seven people, including a 9-year girl, were injured in Kyiv. Missile debris fell in the city centre and an infrastructure facility and several non-residential buildings were damaged, causing a fire, he said.

Klymenko said a hotel and several shopping kiosks were damaged in Cherkasy in central Ukraine and seven people were injured.

The interior ministry and regional officials reported blasts in Cherkasy, Kharkiv, Khmelnytskiy, Rivne, Vinnytsia, Lviv and Ivano-Frankivsk regions.

Maksym Kozytskyi, Lviv's regional governor, said three Russian missiles hit the city of Drohobych in the west, about 60 kilometres from the Polish border.

Kozytskiy said an infrastructure facility and warehouses were hit.

In a separate overnight attack, two people were killed by Russian shelling of a dormitory in the southern city of Kherson, governor Oleksandr Prokudin said.
