The War on War coalition to disarm militarism invites you to join them "from June 20th to 22nd in Bobigny [Paris suburb] to build an anti-militarist, anti-imperialist, and anti-colonial front", to "stop genocide, the war economy and the merchants of death".
I would expect further details on their website:
guerrealaguerre.net (in French)

One of the listed participants is Rima Hassan, Member of European Parliament (MEP), so presumably that is pending if Israel ends their illegal abduction of the MEP before then. Not that the EU seems to care about their parliamentarians, if they're against genocide that is.
