Preparations for the rally
The rally Sunday is also a huge security challenge for a nation on alert for more violence, after 17 people and three gunmen were killed over three days of attacks on a satirical newspaper, a kosher supermarket and on police that has shaken France.
More than 2,000 police are being deployed, the Associated Press reported in addition to tens of thousands already guarding synagogues, mosques, schools and other sites around France.
Hundreds of thousands of people marched Saturday in cities from Toulouse in the south to Rennes in the west to honor the victims, and Paris expects hundreds of thousands more at Sunday’s unity rally.
Unity against extremism is the overriding message for Sunday’s rally.
Top European and U.S. security officials are also holding a special emergency meeting in Paris about fighting terrorism.
The rally "must show the power, the dignity of the French people who will be shouting out of love of freedom and tolerance,” Prime Minister Manuel Valls said Saturday.
"Journalists were killed because they defended freedom. Policemen were killed because they were protecting you. Jews were killed because they were Jewish,” he said. "The indignation must be absolute and total - not for three days only, but permanently.”
Al-Qaeda’s branch in Yemen said it directed Wednesday’s attack against the publication Charlie Hebdo to avenge the honor of the Prophet Muhammad, a frequent target of the weekly’s satire.
