BBC News – More than three million people have taken part in unity marches across France after 17 people died during three days of deadly attacks in Paris.
Up to 1.6m are estimated to have taken to the streets of the French capital.
More than 40 world leaders joined the start of the Paris march, linking arms in an act of solidarity.
The marchers wanted to demonstrate unity after the attacks on satirical magazine Charlie Hebdo, police officers, and a kosher supermarket.
The French government said the rally turnout was the highest on record.
The rally, led by relatives of the victims of last week’s attacks, began at the Place de la Republique and concluded in the Place de la Nation.
Several other French cities also held rallies. The interior ministry said turnout across France was at least 3.7 million, including up to 1.6 million in Paris – where sheer numbers made an exact tally difficult.
Rallies also took place outside of France, with thousands of people gathering in London, Washington, Montreal and Berlin.
In Madrid, several hundred Muslims held banners saying “Not in our name” next to the train station where in 2004 Islamist bombings killed nearly 200 people.
World leaders, including British Prime Minister David Cameron, German Chancellor Angela Merkel, Israeli Prime Minister Benjamin Netanyahu, Palestinian President Mahmoud Abbas, Malian President Ibrahim Boubacar Keita, EU President Donald Tusk, and Jordan’s King Abdullah II joined the beginning of the Paris march.
“Paris is the capital of the world today,” French leader Francois Hollande said.
The leaders observed a minute’s silence before the march began.
About 2,000 police officers and 1,350 soldiers – including elite marksmen on rooftops – were deployed in the capital to protect participants.
The Paris march was split into two routes for security purposes.
Marchers chanted “liberte” (“freedom”) and “Charlie”, in reference to Charlie Hebdo magazine.
Some waved French flags, cheered, and sang the national anthem.
Samia Ghali, mayor of one of Marseille’s districts, told the BBC that people there were marching for tolerance and co-existence. Marseille is the city with the largest Muslim population in France.
So many people were crammed into the Place de la Republique that it created a bottleneck. Some marchers had to filter down side streets to reach the Place de la Nation for the final rally.
They streamed past the cafe where I was working, wrapped against the chill as the sun went down, so many faces beaming with pride, voices still not too hoarse for another yell of “Charlie!” Their hands must have been sore from clapping.
“This is serious, this was an attack on freedom, we cannot allow this,” said Laurent. The march was so crowded it took him, his wife Isabelle and his daughter Coline two hours to walk just 2km (1.2 miles).
“Our values are liberty, equality and fraternity and we cannot allow terrorists to dictate to us,” he added.
“We had to get into the streets to show we are not afraid,” said Isabelle.
