World leaders including Muslim and Jewish statesmen linked arms to lead more than a million French citizens through Paris in an unprecedented march to pay tribute to victims of Islamist militant attacks.
Commentators said the last time crowds of this size filled the streets of the capital was at the Liberation of Paris from NaziGermany in 1944.
President Francois Hollande and leaders from Germany, Italy,Turkey, Britain as well as Israel and the Palestinian territories moved off from the central Place de la Republique ahead of a sea of French and other flags.
Seventeen people, including journalists and police, were killed in three days of violence that began on Wednesday with a shooting attack on the political weekly Charlie Hebdo, known for its satirical attacks on Islam and other religions.
Giant letters attached to a statue in the square spelt out the word Pourquoi?” (Why?) and small groups sang the “La Marseillaise” national anthem.
“Paris is today the capital of the world. Our entire country will rise up and show its best side,” Hollande said.
At least 3.7 million people took part in silent marches throughout the country, the biggest public demonstration ever registered inFrance. A total of 1.2 million to 1.6 million marched in Paris and a further 2.5 million in other cities, the Interior Ministry said.
The marches mostly proceeded in a respectful silence, reflecting shock over the worst militant Islamist assault on a European city since 57 people were killed in an attack on London’s transport system in 2005.
The attackers, two French-born brothers of Algerian origin, singled out the weekly for its publication of cartoons depicting and ridiculing the Prophet Mohammad. The bloodshed ended on Friday with a hostage-taking at a Jewish deli in which four hostages and the gunman were killed.
Some 2,200 police and soldiers patrolled Paris streets to protect marchers from would-be attackers, with police snipers on rooftops and plain-clothes detectives mingling with the crowd.
German Chancellor Angela Merkel, British Prime Minister David Cameron and Italian Prime Minister Matteo Renzi were among 44 foreign leaders marching with Hollande.
