DAMASCUS, Syria – Syrian air defenses opened fire on Israeli aircraft that violated Syrian airspace, a Syrian military spokesman said Thursday.

The spokesman, quoted by the official Syrian Arab News Agency, did not say how the Syrian military fired on the aircraft or where the incident happened, other than saying it occurred at midnight Wednesday.

“We warn the Israeli enemy government against this flagrant aggressive act, and retain the right to respond in an appropriate way,” the Syrian spokesman said.

It was not clear if Syria was accusing the Israelis of using warplanes or some type of other aircraft such as drones.
