The Commander-in-Chief of Ukraine's armed forces, Valerii Zaluzhnyi, said Tuesday that the military has seen “certain gains” in its offensive and is “moving forward.”

He said he informed the United States’ top General Mark Milley, Chairman of the Joint Chiefs of Staff, about the situation along the frontline in a phone call.

“Both defensive and offensive fierce fighting is ongoing in the East and South of our nation. We have certain gains, implementing our plans, moving forward,” Zaluzhnyi said in a Facebook post.
