The US military fired more than 50 tomahawk missiles at the al-Shayrat military airfield near Homs at 1.40am today. Russia was informed of the airstrike about 30 minutes in advance, according to Moscow's ambassador to the UN.
Now a Syrian military source has claimed that it had already 'learned of the American threat' and that precautions were taken 'in more than one military point'. The source did not say how they knew or who had informed them.
'We learned of the American threat and the expected military bombardment on Syrian territory,' a source told AFP.
