"There is a lot of work to be done," he said in his nightly video address on Thursday, as quoted by Ukrainian state news agency Ukrinform.
"Cities like Kharkiv, regions like Donetsk and Zaporizhzhia need more systems, more security," he added. "This is the task of all our diplomats, of our entire state. I thank everyone who is effective in this."
'Ukraine is constantly getting stronger'
Zelensky told the nation: "Not everything can be told publicly now. But what is absolutely certain is that Ukraine is constantly getting stronger. Our air defense capabilities are increasing."
He thanked "all the defenders of the sky who are on combat duty every night and every day, all pilots and engineers of the Ukrainian Air Force, all anti-aircraft gunners and soldiers of mobile fire groups," the Ukrinform news agency reported.
Zelensky said in late October that Ukraine was preparing for a new wave of Russian air strikes on energy infrastructure.
Russia invaded Ukraine on February 24, 2022, launching the largest military campaign in Europe since World War II.
Thursday is day 631 of Russia’s war on Ukraine.
