Russian shells pummeled the southern Ukrainian city of Kherson on Saturday, killing at least 10 people and injuring 55 in the city that Moscow’s troops were forced to abandon last month.

Ukrainian President Volodymyr Zelenskyy, just back from his quick trip to Washington, posted photos of the wreckage on his social media accounts. He noted the destruction came as Ukrainians were beginning Christmas celebrations that for many Orthodox Christians will culminate in the traditional celebration Jan. 7.

“This is not sensitive content — it’s the real life of Kherson,” Zelenskyy tweeted. The images showed cars on fire, bodies on the street and building windows blown out.

Yaroslav Yanushevych, the governor of the Kherson region, said in televised remarks that the number of people killed in the latest shelling of the city has risen from seven to 10.

He added that 55 people were wounded, 18 of them in grave condition. Yanushevych said scores of others, including a 6-year-old girl, were wounded by Russian shelling a day earlier.

Saturday marks 10 months since the start of the Russian invasion.

Ukraine has faced a blistering onslaught of Russian artillery fire, missiles, shelling and drone attacks since early October, much of it targeting the energy infrastructure in a bid to cut electricity and heating services as the freezing winter advances. The shelling has been especially intense in Kherson since Russian forces withdrew and Ukraine’s army reclaimed the city in November.
