Saudi Arabia, a supporter of rebels fighting to topple President Bashar al-Assad, has raised its level of military alertness in anticipation of a possible Western strike in Syria, sources familiar with the matter said on Friday.
The United States has been calling for punitive action against Assad's government for a suspected poison gas attack on a Damascus suburb on August 21 that killed hundreds of people.
Saudi Arabia's defense readiness has been raised to "two" from "five", a Saudi military source who declined to be named told Reuters. "One" is the highest level of alert. "It is a must, no one knows what will happen," he said.
The source said other countries in the region, including Jordan, Turkey and Israel, appeared also to have raised their level of military readiness.
