Russians were told ahead of time so they would not be where the missiles landed, causing damage a bulldozer can repair shortly.

for the real reason of the missile attack. Most of the missiles hit an Anunnaki alien hive that not long ago devoured an entire Russian Spetznatz Special Forces unit except for one who escaped to tell about it. Only 26 missile hit the Syrian base. The rest, most of them, hit the alien hive. There are Anunnaki hives all over the world and they eat humans. Afgans thrown the disabled into Anunnaki caves to be devoured.
