In Douma, last Saturday, a chemical weapons attack killed up to 75 people, including young children, in circumstances of pure horror.
Mrs May said chemical weapons had all too often been used in recent times.
In a statement released on Facebook, Corbyn, who is also the head of Labour Party, said: "Theresa May should have sought parliamentary approval, not tailed after Donald Trump".
On the 7th April, reports emerged from Douma in Syria that a chemical weapons attack had taken place, very quickly the US pinned the blame on Bashar al-Assad and just 7 days later, the coalition of the US, UK and France made a decision to bomb Syria.
"This evening I have authorised British armed forces to conduct coordinated and targeted strikes to degrade the Syrian regime's chemical weapons capability and deter their use".
In a statement Friday night, U.S. President Donald Trump outlined strikes being carried out against the Syrian regime of Bashar al-Assad after a chemical weapon attack earlier in the week.
"The American (military) knows well that going towards a wide confrontation and a big operation against the regime and the army and the allied forces in Syria could not end, and any such confrontation would inflame the entire region", Nasrallah said. "As other nations step up their contributions we look forward to the day we can bring our warriors home".
"America does not seek an indefinite presence in Syria", he said, thanking the United Kingdom and France for joining the U.S. in its fight against the Syrian regime.
However, there have been plenty of MPs, including some Conservatives opposed to action in 2013, who have publicly backed the prime minister.
None of the air strikes hit zones where Russian air defense systems protect the Russian bases of Tartus and Hmeimim, Russian news agencies cited the Ministry of Defense as saying.
"The fact of this attack should surprise no one. And so to achieve this there must also be a wider diplomatic effort - including the full range of political and economic levers - to strengthen the global norms prohibiting the use of chemical weapons which have stood for almost a century", May said.
Armed forces from the United Kingdom, the U.S. and France have fired missiles to destroy what they say are chemical weapons factories in Syria.
But in reality, the airfield targeted previous year resumed operations shortly after the attack and, according to Western intelligence, chemical attacks resumed with impunity.
"We want to re-establish that global norm that chemical weapons are banned and should not be used", May said. Nevertheless, the British government is firmly behind the USA president, Donald Trump, who has already told the Syrians and Russians that missiles "are coming". "Russian air defence units did not participate as no missile entered their areas of responsibility", the embassy's spokesperson told reporters when asked to comment on Williamson's words.
The Syrian government and Russian Federation called this information untrue, while the United States and allies have blamed Bashar al-Assad for the attack.
Overnight, US, British and French forces launched more than 100 missiles from ships and manned aircraft, targeting three of Syria's main chemical weapons facilities.
