Missile attacks hit energy facility in Odesa and ‘objects of critical infrastructure’ in Kharkiv, governors say.

Russia has unleashed a barrage of missiles on cities across Ukraine, including the capital, Kyiv, the Black Sea port of Odesa and the northeastern city of Kharkiv, according to Ukrainian officials and media reports.

The missile attacks set off air raid sirens all across Ukraine early on Thursday.

In Kyiv, Mayor Vitali Klitschko reported explosions in the city’s southern Holosiivskyi district.

“All services heading to the spot,” he wrote on social media.

Power supply has been cut pre-emptively to about 15 percent of Kyiv residents, he added.

In eastern Ukraine, 15 missiles struck the city of Kharkiv and the outlying region, hitting residential buildings, according to Governor Oleh Syniehubov. He promised to reveal more details about the scale of the damage or any casualties in Ukraine’s second-largest city.

“Objects of critical infrastructure is again in the crosshairs of the occupants,” he said in a Telegram post.

Kharkiv Mayor Ihor Terekhov reported on Telegram that there were “problems with electricity” in some parts of the city.

In the Odesa region, Governor Maksym Marchenko said on Telegram that a mass missile attack had hit an energy facility in the port city, cutting off power.

Anti-aircraft units had downed some missiles and new attacks could follow, he said, urging residents to stay in shelters.

“Fortunately, there are no casualties. Electricity restrictions are in effect,” the governor added.

Ukrainian Railways reported power outages in certain areas. Five trains were delayed by more than one hour, and 10 trains were delayed by more than 30 minutes.

Preventive emergency power cuts were applied in Kyiv, Dnipropetrovsk, Donetsk and Odesa regions, supplier DTEK said.

More explosions were reported in the northern city of Chernihiv and the western Lviv region, as well as in the cities of Dnipro, Lutsk and Rivne.

Ukrainian media also reported explosions in the western regions of Ivano-Frankivsk and Ternopil.

Russia has been hitting Ukraine with waves of missile attacks since last October.

Initially, the barrages targeting the country’s energy infrastructure took place weekly, plunging the entire cities into darkness, but became more spread out in time, with commentators speculating that Moscow may be saving up ammunition.

The last barrage took place on February 16.
