Is Turkey going to war with Syria and Iran now?

The Syrian military has admitted it shot down a Turkish fighter jet - claiming the aircraft had been flying inside Syria's territorial waters.

The revelation comes after hours of confusion as to what happened to the plane and its pilots.
Turkey says it will "take the necessary decisive measures once it has all the details" of what occured.
Turkey's military earlier announced it had lost contact with the F4 jet while it was over the sea off the southeastern coast, near the Syrian border.
Earlier, in his first public comments on the warplane's loss, Turkish prime minister Tayyip Erdogan told reporters that he could not say whether the plane had crashed or been shot down.
