Commentators said the last time crowds of this size filled the streets of the capital was at the Liberation of Paris from Nazi Germany in 1944.

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.
