Jan. 9 (UPI) -- At least four people were killed and 19 injured after Russia launched large-scale strikes against Kyiv and across Ukraine overnight, with Moscow admitting it used a nuclear-capable hypersonic missile for only the second time ever.

The fatalities, all in Kyiv, included a paramedic who was killed when an apartment building where he was treating people in Darnytskyi district in the east of the capital was hit again in a so-called "double tap" strike that also injured four other paramedics, said Kyiv Mayor Vitali Klitschko.

At least four neighborhoods were targeted with drones, damaging at least 20 residential buildings, as well as commercial buildings, in the Dniprovskyi, Pechersk and Desnianskyi districts and a fire in the Shevchenkivsky district.

The power and water supply were also interrupted in parts of the city amid heavy snowfall and temperatures of 14 degrees Fahrenheit. Metro services linking west and east Kyiv under the Dnipro River were also affected.

President Volodymyr Zelensky said in an online post that the Embassy of Qatar was damaged in the attacks involving 242 drones and 35 ballistic and cruise missiles targeting energy facilities and civilian infrastructure across the surrounding Kyiv and Chernihiv regions and in the far western Lviv province, which was hit with an Oreshnik hypersonic intermediate range ballistic missile.
