Russia is currently attacking the northern and southern borders of Ukraine through artillery fire and land invasion.
The border guard service while revealing the development on Thursday added that Ukrainian forces are returning fire.
According to the guards, the Russian forces are receiving support from Belarus, adding that an attack has been launched from Crimea, the Russian-occupied peninsula region on Ukraine’s southern flank.
The border guards said, “Attacks on border units, border detachments and checkpoints are carried out with the use of artillery, heavy equipment and small arms.
“The work of enemy sabotage and reconnaissance groups is also recorded.”
A Ukrainian interior ministry official in a statement released on Thursday reported the fall of the previously government-held town of Shchastya, on the eastern frontline with a rebel-held enclave.
