Stuff News Magazine said US President Donald Trump has left the door open to further strikes against targets in Syria after the United States in conjunction with France and Britain targeted chemical weapons sites and military installations with a barrage of missiles.
In an address, Trump said the attack had been undertaken "to establish a strong deterrent against the production, spread and use of chemical weapons". But he added: "We are prepared to sustain this response until the Syrian regime stops its use of prohibited chemical agents."
He said the actions of Syrian President Bashar al-Assad were not the work of a man, but the "crimes of a monster instead".
The strikes have raised global fears of possible conflict between Russia, a key ally of Syria, and the US. Just a week earlier, Trump had shocked his own security chiefs by abruptly announcing his intention to rapidly remove US troops from Syria, where they have been fighting IS militants.
