Photographs from the morning of October 30, several hours before Israel allegedly struck a military base in Syria, reveal the presence of newly upgraded Russian anti-aircraft missiles and indicate that the US defense establishment, which hastily ordered the satellite photos from a civilian contractor, was given advance warning about the air strike.

Taken at 10 a.m., roughly nine hours before the strike, the photos show two possible targets: an upgraded and deployed battery of S-125 missiles and six very large trailers that could carry missiles. The photos were first published by intelligence analyst Ronen Solomon along with a co-authored accompanying article in Israel Defense magazine.

The S-125 battery, the photos revealed, had been upgraded to a point that it posed a serious threat to Israeli or US aircraft and could, like the US-made Patriot systems, destroy incoming cruise missiles.
