The United States, Britain, and France conducted "precision strikes" on Syria on Friday in response to a suspected chemical weapons attack that reportedly killed dozens in the rebel-held town of Douma.
The Pentagon said the strikes hit three targets believed to have been involved in creating chemical weapons.
The sites included the Barzah Research and Development Center near Damascus and the Him Shinshar chemical weapons complex near Homs.
The U.S. military said the strikes "destroyed" Him Shinshar's chemical weapons storage facility and damaged the chemical weapons bunker.
Defense Secretary James Mattis said "nothing is certain" when asked whether he believed the strikes would deter Syrian President Bashar Assad from using chemical weapons again.
"It was done on targets that we believed were selected to hurt the chemical weapons program. We confined it to the chemical weapons-type targets," he said.
Here are satellite photos showing what the sites looked like before and after the strikes:
