Trump later posted to Truth Social adding "there will be very serious retaliation."
"This was an ISIS attack against the U.S., and Syria, in a very dangerous part of Syria, that is not fully controlled by them," he wrote in the post. "The President of Syria, Ahmed al-Sharaa, is extremely angry and disturbed by this attack. There will be very serious retaliation. Thank you for your attention to this matter!"
