The Labour leader criticised Theresa May for failing to recall Parliament before giving the go-ahead for British bombers to join the US-led air strikes on Syria.
The Labour leader said: "I think parliament should have a say in this and I think the Prime Minister could have quite easily done that".
Foreign secretary Boris Johnson said the air strikes were created to deter Bashar al-Assad's regime and others around the world from using chemical weapons.
And Britain should press for an independent UN-led investigation of last weekend's horrific chemical weapons attack so that those responsible can be held to account.
Mr Corbyn said the air strikes may have been illegal, despite the government's assertion that it was allowed under global law to take military action to alleviate overwhelming humanitarian suffering.
"There is precedent over previous interventions when Parliament has had a vote".
Asked how the United Kingdom would respond to fresh chemical weapons attacks, he said: "With allies, we would study what the options were".
The Prime Minister said she judged the operation to be in Britain's national interest, adding that there was "no practicable alternative to the use of force".
Some 75 people, including children, are said to have died when the Syrian regime used chlorine gas and another nerve agent in Douma last Saturday.
Assad and Russian Federation deny using chemical weapons, the trigger for the strikes early on Saturday.
Shadow foreign secretary Emily Thornberry said taking military action against the Assad regime had been the "wrong thing to do".
Downing Street insisted on Friday that there was no set timetable for any potential military action to begin.
But British involvement in further military intervention is controversial at home, in a country still haunted by its role in the US-led invasion of Iraq.
The group said it "strongly condemned" the action and accused May of "sanctioning killing" at US President Donald Trump's behest.
Her office said that she had talked with Mr Trump by telephone on Thursday evening to discuss Syria.
North Atlantic Treaty Organisation allies have given the action their full support, secretary general Jens Stoltenberg said.
Asked whether Labour did not believe in military action in any circumstances, she said: "No". "It's never pointless calling for that, anything that brings a cessation of the use of chemical weapons moves us nearer, if not totally to, a ceasefire and a reopening of the Geneva talks which has got to be the right way forward", he said.
MPs are due to return to Westminster from the Easter recess on Monday - and a row is continuing between some MPs over whether a vote should take place in Parliament before any action is taken.
