The Ukrainian President Volodymyr Zelensky accused Russian leader Vladimir Putin of using Ukraine as a "training ground".
He made his remarks after Kiev announced this morning that an intercontinental ballistic missile (ICBM) had been fired from Russian territory for the first time since the start of the war.
"Today our crazy neighbor again showed what he really is and how he despises the dignity, freedom and life of people in general," Zelensky wrote in "Telegram".
"Putin is so afraid that he is already using new missiles,", emphasized the Ukrainian president, adding that an investigation is currently underway in connection with the launch of the missile.
"It is obvious that Putin is afraid when around him a normal life is just going on,", noted Zelensky.
Tensions between the two countries escalated further after Washington allowed Kiev to use American missiles to strike targets on Russian territory.
The Russian Ministry of Defense announced today that it had intercepted two British long-range Storm Shadow cruise missiles.
