An emboldened Russia has ramped up military offensives on two fronts in Ukraine. That is 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).

For months the talk in Kyiv was of a much-anticipated Russian offensive that would aim to gobble up more of Ukraine’s eastern regions. So far, it’s been underwhelming – but the Russians have made some gains and vastly reinforced their troop numbers in some areas.
