After several days of expressing concern but by no means saber-rattling over the Turkish F-4 shot down by Syria. Turkey is now talking tougher, saying it is changing its rules of engagement and that if Syrian forces approach the Turkish border, that will be considered a threat.
Turkey admits the aircraft entered Syrian airspace over the Mediterranean but now says it then was ordered to leave by Turkish controllers and was 24 kilometers or 13 nautical miles from shore when downed, outside Syrian territorial waters.
The flight path shown by Syria suggests the aircraft was circling off the Syrian coast, possibly on a reconnaissance mission to gather electronic intelligence. Turkey has indicated it was on a training mission to test radar.
Turkey appears to have waited until it had the opportunity to consult with its NATO allies before taking a somewhat more threatening stance on the downed aircraft.
