The UK Defense Ministry confirmed on September 19 that the UK participated in the US-led coalition’s air strike on the Syrian army near the Syrian city of Deir Ezzor on September 17.
The minstry said it “would not intentionally target Syrian military units.” …however, it did.
We recall, 62 Syrian soldiers were killed and over 100 injured as result of bombing by the US-led coalition air power. The ISIS advance followed air raids against the Syrian government forces.
