The U.S. says the missiles were a response to Syria's use of chemical weapons. The move could raise tensions with Russia, which backs Syria's President.
The full transcript of an address made by US President Donald Trump following the air strikes he ordered against Syria has been released.
This week Bashar al-Assad launched a horrible chemical weapons attack on innocent civilians.
Using a deadly nerve agent, Assad choked out the lives of helpless men, womenand children. It was a slow and brutal death for so many.
Even beautiful babies were cruelly murdered in this very barbaric attack.
No child of God should ever suffer such horror.
Tonight, I ordered a targeted military strike on the airfield in Syria from where the chemical attack was launched.
It is in this vital national security interest of the United States to prevent and deter the spread and use of deadly chemical weapons.
There can be no dispute that Syria used banned chemical weapons, violated its obligations under the chemical weapons convention and ignored the urging of the UN Security Council.
Years of previous attempts at changing Assad's behaviour have all failed and failed very dramatically.
As a result, the refugee crisis continues to deepen and the region continues to destabilise, threatening the United States and its allies.
Tonight, I call on all civilised nations to join us in seeking to end the slaughter and bloodshed in Syria.
