On April 28, around noon, according to one report, Mr. Gennady Kernes, mayor of the eastern Ukraine city of Kharkiv, went for a cross-training jog in a city park.

En route, an assassin shot the mayor in the back. According to his bodyguards, a sniper fired at Kernes from long range. Hitting the back of a running man at a distance — the upper body mass, to use the lingo — indicates a crack sniper fired the shot.
