US 'locked and loaded' to strike Syria again if new attack: Haley

The United States is "locked and loaded" to strike again if Assad's government again uses chemical weapons, US Ambassador to the United Nations Nikki Haley told the Security Council.

"We are confident that we have crippled Syria's chemical weapons programme. We are prepared to sustain this pressure, if the Syrian regime is foolish enough to test our will," she said.

"If the Syrian regime uses this poison gas again, the United States is locked and loaded," Haley said. 

"We cannot stand by and watch Russia trash every international norm that we stand for," she added.
