Russia attacked Ukraine with drones and missiles, killing three and injuring at least 16 in the capital overnight into Friday, Ukrainian authorities said.

Russia also struck critical infrastructure in the western city of Lviv using an unidentified ballistic missile, said Mayor Andriy Sadoviy. The Western Command of Ukraine's Air Force later said the missile traveled at a speed of 13,000 kilometers (more than 8,000 miles) per hour, and that the specific type of rocket was being investigated.

Several districts in Kyiv were hit in the attack, said Kyiv City Military Administration head Tymur Tkachenko. In the Desnyanskyi district a drone crashed onto the roof of a multi-story building. At another address in the same district the first two floors of a residential building were damaged as a result of the attack.

In Dnipro district, parts of a drone damaged a multi-story building and a fire broke out.

Running water and electricity were disrupted in parts of the capital as a result of the attack, Kyiv's Mayor Vitali Klitschko said.

The attack took place just hours after Ukrainian President Volodymyr Zelenskyy alerted the nation about Russia’s intentions for a large-scale offensive. He said that Russia aimed to take advantage of the frigid weather in the capital, making roads and streets perilously icy.
