Around 3,000 people demonstrated for Gaza Saturday afternoon deying a ban from French Minister of Interior Bernard Cazeneuve.
The demonstrators assembled in the largely immigrant Barbes area of Paris following a call by the extreme-left New Anti-capitalist Party.
Police prevented them marching into the city centre.
The Interior Minister had banned demonstrations in the French capital, citing the “danger to public order” and referring to on two Paris synagogues after a pro-Gaza demonstration last Sunday.
Protests were also banned in Nice in the south-east and Sarcelles, near Paris.
French President François Hollande earlier threatened that “those who want to demonstrate at any price” could be punished.
