The U.S. Embassy in Saudi Arabia said Wednesday that it has received information that a terrorist group may be planning to abduct Westerners in Riyadh.
The embassy passed along the notice in an emergency message for U.S. citizens.
"The U.S. Embassy in Riyadh reminds all U.S. citizens to exercise prudence and enhanced security awareness at all times," it said.
"We deemed the information to be credible, or would not have issued the emergency message," Deputy State Department spokesman Mark Toner said.
He would not comment on specific intelligence, but said there was no reason for U.S. citizens to leave Saudi Arabia as a result of the message.
