According to Syrian Arab News Agency's reporter, air defences countered a "hostile target" which had breached Syrian air space west of the capital Damascus.
The target was destroyed over Deir al-Ashair area, the state-run news agency said. There were no immediate reports as to what it was.
Previously, Syrian President Bashar Assad said in an interview that Syria will continue beefing up its air defenses.
Assad said back then that he did not exclude another US strike anytime as long as the United States continued to violate international laws.
