The travel ban on French nationals could be imposed "where there are serious reasons to believe that someone is planning to travel abroad to take part in terrorist activities, war crimes or crimes against humanity or in a theatre of operations of terrorist groups and in conditions likely to jeopardise public security upon their return to French territory", according to the text.
Under the scheme approved yesterday, the travel ban may be imposed for six months, renewable for up to two years.
"Six months is a reasonable period because this is a serious measure," said Sebastien Pietrasanta, a deputy with the ruling Socialists, who introduced the bill.
He was responding to an amendment put forward by the conservative opposition UMP party for an initial one-year travel ban.
Anyone targeted by the new laws would have the right to legal redress, though the administration would not be able to reveal any classified information in relation to the case, Interior Minister Bernard Cazeneuve told parliament.
The French move echoes plans under way in neighbouring Britain where Prime Minister David Cameron wants to give border police powers to seize passports from suspected would-be jihadists at the border.
Violation of the new French rules would be punishable by three years in prison and a hefty fine, measures that may also deter those who do manage to sneak out from returning to France.
According to Cazeneuve, around 930 French citizens have been travelling to and from Iraq and Syria recently, a 74 per cent increase in eight months.
Of those 36 were killed while overseas.
Pietrasanta said the new measures would also "save people from themselves", particularly young men and women who have just begun to be radicalised and who risk getting caught up in armed struggles.
The draft law, which also targets messages posted on the Internet, is being rushed through the French parliament and is set to go to a single-round formal vote today.
