The French leader also mentioned the country's position on the use of chemical weapons, saying "France will strike" if - in violation of global treaties - chemical weapons are used against civilians in the Syrian conflict.
"We will strike the place where these launches are made or where they are organised", Mr Macron said.
"Today, our agencies, our armed forces, have not established that chemical weapons, as set out in treaties, have been used against the civilian population", he said.
As soon as the evidence comes, I will do what I said, "adding that" the fight against terrorists, jihadists "is a priority".
Regarding the Syrian regime itself, either during or after the conflict; "it will be answerable to worldwide justice" he added.
PARIS, Feb 14 (Reuters) - Iran's ballistic missile programme must be placed under worldwide surveillance, French President Emmanuel Macron said, in an bid to get tougher on Tehran while preserving the nuclear deal that Donald Trump has threatened to scrap.
Receiving Putin at Versailles in May 2017, Macron had declared that France would respond immediately to any use of chemical weapons in Syria.
The comments came amid unverified reports that pro-government forces have used chlorine on civilians and rebels to gain control of areas.
Following a deadly chemical weapons attack near Damascus in 2013, the United States and Russian Federation agreed a plan with Syria to remove and destroy its chemical weapons stockpile within a year.
On Wednesday last week, Foreign Minister Jean-Yves Le Drian said "all indications" suggest that Assad's forces were using chlorine weapons in the civil war against rebel forces, but being cautious said "we haven't completely documented this".
"Syria's government categorically denies possessing. chemical weapons".
In 2013, for example, there were several attacks which killed dozens of people, after which French Foreign Minister Laurent Fabius asserted that there was "no doubt" that the Syrian regime used the never gas sarin in multiple cases.
"I want a new cycle of negotiations with regional parties and the permanent members of the Security Council, like we did for the nuclear deal, but widening it to regional countries so that we can reduce and eradicate this insecurity", Macron told reporters late on Tuesday.
