Robert Brovdi said Ukrainian strikes had reduced Russian military cargo traffic on the R-280 "Novorossiya" highway by 71% over two weeks. The road links Russia to occupied Crimea through Mariupol, Berdiansk and Melitopol. "We will isolate Crimea in the near future," Brovdi said. The campaign comes as Ukraine steps up attacks on bridges, roads and military infrastructure across Russian-occupied southern Ukraine. Ukrainian forces struck the Chonhar Bridge on June 7 and June 9. Kyiv official Andrii Kovalenko said the latest attack destroyed the crossing.
