The United States on Friday threatened to take further military action in Syria following its missile strikes on an air base in the war-wracked country in retaliation for a suspected chemical attack.
"The United States took a very measured step last night," US Ambassador Nikki Haley told the UN Security Council.
"We are prepared to do more, but we hope it will not be necessary."
The Security Council was meeting in an emergency session to discuss the US actions in Syria that Russia branded a "flagrant violation of international law and an act of aggression" against Syria.
Haley said the air strikes destroyed an air field from which the United States believes the chemical attacks on the rebel-held town of Khan Sheikhun were launched.
"We were fully justified in doing so," she said.
Eighty-six people including at least 27 children died in Khan Sheikhun in an attack the United States has blamed on Syrian President Bashar al-Assad.
"The United States will no longer wait for Assad to use chemical weapons without any consequences," Haley said. "Those days are over."
While threatening further strikes, the US envoy also said it was time to press on with a political solution to the six-year war.
"Now we must move to a new phase: a drive toward a political solution to this horrific conflict." READ MORE
