Russia’s Interfax news agency quoted the Russian Defence Ministry as saying that said two Israeli F-15s had carried out the strike, firing eight missiles from Lebanese airspace. Russia said that Syrian air defences had shot down five of the eight missiles fired, with three hitting the western part of the aerodrome (the Iranian enclave - there are pictures by the Iranian FARS news agency).
But how could two F-15s launch eight missiles - the primary stand off weapon still seems to be Popeye/Have Nap, two of which can be carried. Glide weapons like Spice or JDAM surely wouldn't reach Tiyas from 'Lebanese airspace'?
