From Arutz Sheva:

Israeli TV Channel 1 said Tuesday that the IDF "definitely carried out an attack" against Syria last Thursday. The attack was meaningful, the channel's military affairs reporter said, and was probably carried out against a large and important target that justified taking this kind of extreme action at such a sensitive time in Israeli-Syrian relations.

The target hit was in the Deir Ez-Zour region in eastern Syria, near the Euphrates river.

...

"The Israeli government is very happy with the success of the operation," the sources told CNN. Israeli reporters noted that IDF Chief of Staff Gabi Ashkenazi was smiling from ear to ear at a function held on the evening after the attack and saw this as evidence that the attack had gone well.

Sources in the U.S. government and military said that "they are happy to have Israel carry the message to both Syria and Iran that [Israel] can get in and out and strike when necessary."

Well, I guess that settles the controversy over whether it was an attack or an accidental incursion. Considering where Deir Ez-Zour is, it was no accident. We'll have to wait and see how this plays out.
