Ukraine’s defense minister is urging calm, saying the likelihood of a Russian invasion was “low.”Oleksii Reznikov said the threat of attack has loomed over the country since 2014, the year Russia seized Crimea, but he added: “There are no grounds for panic, fear, flight or packing of bags.”The minister said there are about 115,000 Russian troops near Ukraine’s border, including those deployed to Belarus for war games, but he said no battle groups have been detected along Ukraine’s border with Belarus. He also reiterated earlier assurances that Kyiv doesn’t plan to attack rebel-held areas in the war-torn east of Ukraine or Crimea — something the Kremlin has accused Kyiv of plotting.
