Ukrainian President Volodymyr Zelensky said in an exclusive interview with AFP on Friday he expects Russia to step up its offensive in the northeast and warned Kyiv only has a quarter of the air defences it needs to hold the front line.
Russian forces, which made only moderate advances in recent months, launched a surprise assault in Kharkiv region on May 10 that has resulted in their biggest territorial gains in a year-and-a-half.
