Ukraine, the United States, and seven North Atlantic Treaty Organization (NATO) member countries began the Clear Sky 2018 war games, a twelve-day series of air exercises involving seven hundred troops in western Ukraine.
On Tuesday, ammunition at an arms depot in northern Ukraine began exploding, resulting in widespread fires and the evacuation of more than twelve thousand people from the area. The Ukrainian government deployed aircraft on Wednesday to fight the still raging fires and said it is investigating “possible sabotage.”
