The U.S. Embassy in Saudi Arabia warned Americans on Wednesday about a potential "missiles or drones" attack later today.
In the security alert posted to the embassy’s website, the warning says the attack may be launched in Saudi Arabia’s capital city, Riyadh.
“The Embassy urges American citizens to stay alert, and to immediately review and take necessary precautions,” the warning states.
“If you hear a loud explosion or if sirens are activated, immediately seek cover,” the embassy's warning says among a list of suggested actions to take should the missile attack commence.
