KYIV, Feb 16 - Russia has switched its aerial strike tactics to fool Ukraine’s air defenses, using decoy missiles without explosive warheads and deploying balloons, a senior Ukrainian official said Thursday.

“The Russians are definitely changing tactics” as the war approaches its one-year anniversary, Mykhailo Podolyak, an adviser to Ukrainian President Volodymyr Zelensky, said in an interview with The Associated Press.
