Russian shelling on Thursday damaged a landmark church in the city of Kherson that once held the remains of the renowned 18th-century commander who exerted Russian control through the southeast parts of modern Ukraine and annexed the Crimean Peninsula.

Emergency service said four of its workers were wounded in a second round of shelling as they fought the fire at St. Catherine’s Cathedral. Four other people were wounded in the first shelling attack, which also hit a trolleybus. The church, dating from 1781, is one of the city’s most notable buildings. It was the burial spot for Prince Grigory Potemkin, a favorite of Russian Empress Catherine the Great.
