Russian Jets Target US Military Aircraft Flying Over Syria

The United States military says Russian jets targeted US military aircraft flying over Syria two days in a row this week. The French officials say yesterday Russian planes flew close to American drones near northwest Syria and dropped flares in front of them around 9.30 AM local time. These provocations come after Russian jets flew over an American base in Syria nearly every day in March. But what is Putin doing with these chasing effectively American aircraft with his fighter jets?
