A series of missile strikes were launched against Syria by the US, UK and France in response to the suspected chemical weapons attack in Douma a week ago.
But how has the international community reacted?
President Vladimir Putin says the air strike conducted by the US, UK and France on Syria will only worsen the country's humanitarian crisis.
In a statement issued by the Kremlin, Russian president Putin said Moscow is calling an emergency meeting of the UN security over the strike launched by the US, UK and France.
Mr Putin denounced the strikes as an "act of aggression" that will exacerbate Syria's humanitarian catastrophe.
European Council president Donald Tusk said the European Union "will stand with our allies on the side of justice".
"Strikes by US, France and UK make it clear that Syrian regime together with Russia & Iran cannot continue this human tragedy, at least not without cost."
Beijing opposes the airstrikes against Syria and has accused the US-led operation of complicating efforts to find a solution to the crisis in the country:
Chinese foreign ministry spokeswoman Hua Chunying said in a statement
“Any unilateral military action violates the United Nations charter and its principles and international law and its principles.
"[The strike] is also going to add more factors to complicate the resolution of the Syrian crisis."
China also called for an investigation to take place, into the claims that the Syria government conducted a chemical attack against civilians in Douma.
NATO Secretary-General Jen Stoltenberg said in a statement:
"I support the actions taken by the United States, the United Kingdom and France against the Syrian regime's chemical weapons facilities and capabilities.
"This will reduce the regime's ability to further attack the people of Syria with chemical weapons.
"NATO has consistently condemned Syria's continued use of chemical weapons as a clear breach of international norms and agreements. The use of chemical weapons is unacceptable, and those responsible must be held accountable.
"NATO considers the use of chemical weapons as a threat to international peace and security and believes that it is essential to protect the Chemical Weapons Convention.
"This calls for a collective and effective response by the international community."
Germany's chancellor said the air strikes are a "necessary and appropriate" response to the attack on Douma.
Angela Merkel said the US, Britain and France:
"took responsibility in this way as permanent members of the UN Security Council".
Mrs Merkel said the strikes were needed "to maintain the effectiveness of the international rejection of chemical weapons use and to warn the Syrian regime against further violations".
She had said earlier this week that Germany would not join allied military action against Syrian government forces.
Israel said the strikes against Syria were an “important signal” to Iran, Syria and Lebanese militant group Hezbollah.
A senior Israeli cabinet minister said:
“The use of chemical weapons crosses a red line that humanity can no longer tolerate.”
Yoav Gallant, a member of Israel’s security cabinet, added in a tweet:
“The American attack is an important signal to the axis of evil - Iran, Syria and Hezbollah,” Gallant said.
The Lebanese Shia Islamist political, military and social organisation, who are an ally of the Syrian regime, has condemned the strikes.
The group said in a statement published on its War Media Channel:
“America’s war against Syria, and against the region’s peoples and resistance movement, will not achieve its aims."
Iran's supreme leader Ayatollah Ali Khamenei has branded US President Donald Trump, France's Emmanuel Macron and Britain's Theresa May as criminal after the attacks.
“The attack this morning against Syria is a crime.
"The American president, the French president and the British prime minister are criminals.”
President of the country, Hassan Rouhani told the Tasnim news agency:
“Such attacks will have no result but more destruction … the Americans want to justify their presence in the region by such attacks.”
