Footage released on May 15 shows troops sending a message to Ukrainian President Volodymyr Zelensky.
“We’ve made it Mr President, we are here,” a soldier says in the video, according to a translation.
The defense ministry said the group was a battalion of the 127th Territorial Defense Brigade in Kharkiv.
Kharkiv Governor Oleh Synyehubov said the troops restored a sign at the border.
