Numerous explosions also took place in the cities of Kharkiv, located in eastern Ukraine, and Lviv, near the border with Poland, according to regional officials.

About 90 percent of Lviv was without electricity, Mayor Andriy Sadovyi wrote on Telegram. Trams and trolleybuses were not working, and residents might experience water interruptions, he said.

Meanwhile, the governor of Ukraine’s southern Mykolaiv region, Vitaliy Kim, said five missiles were shot down over the Black Sea.

Ukrainian military officials said two other projectiles were intercepted over the Sumy region, located on the border with Russia in the country’s northeast.

Elsewhere, air defence units shot down 21 missiles in the Odesa region in southwest Ukraine, its governor Maksym Marchenko said

The fragments of one missile hit a residential building, though no casualties were reported, the governor added.

Charles Stratford, reporting from Kyiv, said the nationwide raids represented “one of, if not the largest barrage of attacks” in recent months.
