US President Donald Trump personally ordered a targeted missile airstrike on a Syrian airfield suspected of launching a chemical attack on civilians on Tuesday.
Israeli Prime Minister Benjamin Netanyahu has come out in support of the actions by President Trump saying, "Israel fully supports [Trump's] decision."
US House speaker Paul Ryan also supports the actions of the commander-in-chief.
"This action was appropriate and just," he says.
"Resolving the years-long crisis in Syria is a complex task, but Bashar al-Assad must be held accountable and his enablers must be persuaded to change course. I look forward to the administration further engaging Congress in this effort."
Senator Marco Rubio says attacks need to continue.
"What must follow is a real and comprehensive strategy to ensure that Assad is no longer a threat to his people and to US security, and that Russia no longer has free rein to support his regime."
Some quickly condemned the president's actions.
Republican senator Rand Paul says the president went about the attack unlawfully.
"While we all condemn the atrocities in Syria, the United States was not attacked," he says.
"The president needs congressional authorisation for military action as required by the Constitution, and I call on him to come to Congress for a proper debate. Our prior interventions in this region have done nothing to make us safer, and Syria will be no different."
"I support stopping Assad's atrocities, but it's unnerving that Trump changed his position on striking Syria 180 degrees in only 24 hours."
"We don't know what happened or who is responsible for alleged chemical attack but we're bombing Syria anyway."
However, many have also supported the actions of the controversial leaders.
What we know:
- More than 50 tomahawk missiles were launched from US Naval ships
- Targets included runways, aircraft and fuel depots
- Donald Trump said the action was in the "vital national security interest" of the US
- The strike follows a deadly chemical weapons attack on civilians in Syria
- It was the US military's first action in the six-year-old war.
