Ukraine says it has moved troops to "advantageous positions" as Russia intensifies its attacks on the region.

Ukraine has pulled back its troops from several villages in the border region of Kharkiv following continued pressure from Russian forces.

Soldiers had come under heavy fire and moved to “more advantageous positions” in two areas of the north-eastern region, a military spokesman said.

Throughout the course of the two-year war, Ukraine has typically used this type of language to signify a retreat.
