Moscow again struck Ukraine’s energy infrastructure, part of an effort to wear down the country. “In the trenches, there are no holidays,” one man said.

U.S. President Joe Biden said on Wednesday he had asked the Defense Department to continue its surge of weapons deliveries to Ukraine, after condemning Russia's Christmas Day attack on Ukraine's energy system and some of its cities.

Ukraine's air force says it detected 184 missiles and drones, causing damage to energy infrastructure across the country.
