Ukraine's deputy defense minister says "biggest blow" in offensive is yet to come

Ukraine's Deputy Defense Minister Hanna Maliar said the "biggest blow" in Ukraine's military campaign is yet to come, but admitted the operation is difficult as Russia throws all it can to stop the offensive.

"The enemy will not easily give up their positions, and we must prepare ourselves for a tough duel. In fact, that is what is happening right now," Maliar said on the Telegram messaging app.

"The ongoing operation has several objectives, and the military is fulfilling these tasks. They are moving as they should have been moving. And the biggest blow is yet to come."
