Zelenskyy: Russia's energy facilities are legitimate military targets for Ukraine.

According to Zelenskyy's Telegram channel, Russia earns revenue through the energy sector, selling oil and gas, and uses it to finance the war. 

Therefore, Ukraine has two options: to increase weapons production and strike Russian military forces, or to strike their source of revenue—energy facilities.

According to the President's words, these sources are considered a legitimate target for Ukraine because Russia has acted in the same way towards them.
