KYIV, Ukraine (AP) — An emboldened Russia has ramped up military offensives on two fronts in Ukraine, scattering Kyiv’s precious reserve troops and threatening to expand the fighting to a new Ukrainian region as each side seeks an advantage before the fighting season wanes in the autumn.

Moscow's forces made gains in the Kharkiv and Zaporizhzhia regions, according to the Institute for the Study of War (ISW).

Russia ramped up drone attacks on Ukraine dramatically in June, an AFP analysis published Tuesday showed, pressuring the war-torn country's stretched air defence systems and exhausted civilian population.
