Russian fighter jets have been "harassing" American drones over Syria for the third consecutive day this week, The Associated Press reports, citing the US military.

A US military statement says three MQ-9 UAVs were “once again harassed” by Russian fighter jets while flying over Syria for nearly two hours on Friday.
“Russian aircraft flew 18 unprofessional close passes that caused the MQ-9s to react to avoid unsafe situations,” US Air Force Central Command Head, Lieutenant General Alexus Grynkewich, said.
“We continue to encourage Russia to return to the established norms of a professional Air Force so we can all return our focus to ensuring the enduring defeat of ISIS,” Grynkewich added.
