Explosions Ring Out in Kyiv After Days of Relative Calm

KYIV, Ukraine — A series of explosions rang out in central Kyiv on Saturday morning, jolting city residents from a relative quiet that had taken hold in the Ukrainian capital over the last two weeks during a festive holiday period.

Kyrylo Tymoshenko, the deputy head of the Ukrainian president’s office, said the blasts were part of an “attack on critical infrastructure facilities” in the city.

At around 9:45 local time, the mayor of Kyiv, Vitali Klitschko, said that there had been a missile strike on the Dniprovs’kyi district in eastern Kyiv. In a statement posted on the Telegram messaging app, he urged residents to remain in shelters.

Mr. Klitschko later said that pieces of a rocket had fallen in the Holosiiv district, a nonresidential area of the capital, and that no casualties had been reported.
