A source in the Syrian army revealed to the AFP news agency that the Syrian army had received a warning about the American attack a few hours before it was carried out. "We learned that the Americans were about to attack and we took precautionary measures in several military compounds, including the base that was attacked, and we transferred several aircrafts to other locations."
This source failed to mention who warned the Syrian government.
Thus far, it was only known that the US had informed Russia and some of its allies, including Israel, of its intention to attack.
Meanwhile, Hezbollah responded for the first time to the American attack on Syria, its biggest ally, and said that US President Donald Trump's move was a foolish step that would only lead to great danger and tension in the Middle East, which serves Israel's interests.
