Ukrainian President Volodymyr Zelenskyy says the war with Russia is in a new stage, with winter expected to complicate fighting after a summer counteroffensive that failed to produce desired results due to enduring shortages of weapons and ground forces.

Despite setbacks, however, he said Ukraine won’t give up.

“We have a new phase of war, and that is a fact,” Zelenskyy said in an exclusive interview with The Associated Press in Kharkiv, in northeastern Ukraine, after a morale-boosting tour of the region, Report informs.

“Winter as a whole is a new phase of war.”

Asked if he was satisfied by the results of the counteroffensive, he gave a complex answer.

“Look, we are not backing down, I am satisfied. We are fighting with the second (best) army in the world, I am satisfied,” he said, referring to the Russian military.
