The groups called on "Muslim citizens of France to observe a minute of silence today at midday, along with the rest of the nation, in memory of the victims of terrorism."
The appeal -- issued by Muslim assemblies from across France -- also called on imams at Friday prayers to "condemn the violence and the terrorism with maximum firmness."
Muslim citizens were also asked to join "in massive numbers" a national day of solidarity on Sunday where demonstrators are expected to take to the streets of towns across France.
