Syrian military rejected reports of a missile attack on Shayrat Airbase in the western province of Homs on Tuesday, hours after state media decried another "aggression" on Syria and said its forces shot down several missiles.

"Last night, a false alarm that Syrian air space had been penetrated triggered the blowing of air defence sirens and the firing of several missiles," a military source told state news agency SANA."There was no external attack on Syria," the source added.

The false report came just days after the US, France and Britain conducted a coordinated missile attack against Syrian government targets. This area has also been targeted by the Israeli air force in the past.
