Shelling Across the Syrian-Turkish Border

Shots fired both ways across the Syrian-Turkish borders, and tonight Turkey has called for UN action (though what that might be is unclear at the moment).  From the letter delivered to the Security Council by the Turkish envoy Ertugrul Apakan:

"This is an act of aggression by Syria against Turkey. It constitutes a flagrant violation of international law as well as a breach of international peace and security."

Turkey, you'll recall, has been a member of NATO for 60 years.  Anyway ... Good grief, people.  I was hoping that the only bombshells of the day would be the purely verbal ones lobbed in the presidential debate.
