"Ukraine has strengthened defense of energy objects, but it is not always enough to defeat all attacks of Russia," said Ukrainian President Volodymyr Zelenskyy in his interview to local telemarathon, Paralel.Az reports.

"They will want to destroy our system until the end. It is their dream. I believe we will be able to cope with it.

Due to lack of air defense systems, we have to choose which object, which city to defend," added Zelenskyy.
