An official source at the Ministry of Foreign Affairs expressed the Kingdom of Saudi Arabia's strong support for the military operations carried out against military targets in Syria, which came in response to the use of chemical weapons by the Syrian regime against innocent civilians that caused the deaths of scores of people, including women and children.
The source noted the ongoing horrible crimes being committed by this regime over many years against the Syrian people.
The official source places the responsibility for these military operations squarely on the Syrian regime.
The source also commended this courageous decision taken by U.S. President Donald Trump to respond to the Syrian regime’s crimes against its people in light of the failure of the international community to stop it from brutalizing its people.
