The Ukraine war front line remained largely frozen in June, extending a longer-term trend of stalled Russian momentum, an analysis of data from the Institute for the Study of War (ISW) carried out by the AFP news agency showed on Friday.
The June data showed a Russian net gain of 30 square kilometres, focused in the northeastern Kharkiv region.
But those gains were largely down to previous Russian incursions being upgraded to advances, as more evidence came to light, said the ISW.
Ukrainian forces gained 11 square kilometres in the southern Zaporizhzhia region and 18 square kilometres in the central Dnipropetrovsk region.
"The extent and scope of the ongoing Ukrainian counterattacks in these oblasts are unclear," said the ISW's Geospatial Intelligence Team.
