The head of world football said: "In our world so disturbed, often hostile and violent, I will say only one thing this evening . . and in French: We do not yet know the true power of peace, nor the true power of football.
"This evening we are all a little bit French, which only increases our sympathy for our neighbours who have been so deeply scarred by the violent events of recent days. So allow me to repeat my appeal of peace and tolerance".
Blatter was speaking in response to the killing spree by Islamic extremists which left 17 people dead in France last week.
The Swiss noted that Monday's ceremony to crown the world player of the year had its roots in France.
"If this evening has a touch of France about it, it's because the Ballon d'or first saw the light of day in France," he said.
"Let us not forget that it was created in 1956 by my friends at France Football (magazine)."
