She also said the USA would "never" agree to direct talks with the Syrian regime, saying the government of President Bashar Assad is "not worthy" of one-on-one engagement.
"The United States and our allies will continue to stand up for truth, accountability, justice and an end to the use of chemical weapons", Haley said.
But despite that warning there was little sign in the debate that followed - particularly between the USA and Russian Federation - that tensions over the Syrian crisis have reached a peak.
The sanctions are the latest effort by the United States to punish the Assad regime and its allies for a chemical weapons attack that killed dozens of civilians two weeks ago. "And Russia did the opposite", she said. "Of course, we clearly heard her words with a great deal of concern and a great deal of sadness". Further, Russian military police forces deployed to the region could not find anyone in Douma's hospitals suffering the effects of a chemical attack. We were not looking to kill people.
"It's impossible to say at this point the mission has been accomplished", King, who caucuses with Democrats, said on CNN's "State of the Union".
The British and French officials at the meeting joined Haley in defending their countries' actions, calling the strikes "limited, targeted and effective" and claiming they had evidence of Assad's responsibility for the chemical attack, with French ambassador François Delattre saying the gas attack tested "the threshold of the global community's tolerance". "We are going to watch out for the best interests of the American people".
US military officials said an initial assessment showed every one of the missiles struck its target on Saturday, reducing the facilities to rubble while avoiding any civilian casualties.
"We should not be condemning the country or group of countries that might actually have the courage to stand up in defense of our common principle - the principle against the use of chemical weapons", Haley said. "That doesn't mean that the Syrians can't re-create the chemical weapons to use again". But late Saturday, senior administration officials called the evidence "incontrovertible".
