Israeli jets scrambled to intercept a drone that crossed into Israeli airspace Saturday from the Mediterranean Sea, bringing it down without incident in the south of the country, a military spokeswoman said.

Lieutenant Colonel Avital Leibovich said Israeli systems on the ground alerted the air force to the drone Saturday morning. She said it flew over the Gaza Strip but did not originate from the Palestinian territory. She said Israel didn’t know the drone’s starting point and an investigation was under way. Nobody was hurt in the incident.
What are the chances of this being a Nato/American drone?

If it is somebody is going to have some explaining to do.
