Q: PARIS (AP) — France's Interior Ministry said the Paris rally for unity against terrorism on Sunday was the largest demonstration in France's history — a march organized to show harmony after three days of attacks that left 17 dead.

 Calling the rally "unprecedented," the ministry said the demonstrators were so numerous they spread beyond the official march route, making them impossible to count. 
  
 French media estimate up to 3 million are taking part, more than the numbers who took to Paris streets when the Allies liberated the city from the Nazis in World War II. 
  
 "It's a different world today," said Parisian Michel Thiebault, 70. He was among a crowd wildly cheering police as their vans made their way through the crowd — a sound unheard of at the frequent protests held in France, where police and demonstrators are often at odds. 
  
 Their arms linked, more than 40 world leaders headed the somber procession, setting aside their differences for a manifestation that French President Francois Hollande said turned the city into "the capital of the world." 
  
 Israeli Prime Minister Benjamin Netanyahu stood near Palestinian President Mahmoud Abbas. Ukrainian President Petro Poroshenko and Russian Foreign Minister Sergey Lavrov also marched. 
  
 Demonstrations were also held in cities around France and around the world. 
  
 The deadly attacks on a satirical newspaper, kosher market and police marked a turning point for France that some compared to Sept. 11. In the weeks and months ahead, the cruelty will test how attached the French — an estimated 5 million of whom are Muslims — really are to their liberties and to each other. 
  
 "Our entire country will rise up toward something better," Hollande said. 
  
 The aftermath of the attacks remained raw, with video emerging of one of the gunmen killed during police raids pledging allegiance to the Islamic State group and detailing how the attacks were going to unfold. Also, a new shooting was linked to that gunman, Amedy Coulibaly, who was killed Friday along with the brothers behind a massacre at satirical newspaper Charlie Hebdo in nearly simultaneous raids by security forces.

 The aftermath of the attacks remained raw, with video emerging of one of the gunmen killed during police raids pledging allegiance to the Islamic State group and detailing how the attacks were going to unfold. Also, a new shooting was linked to that gunman, Amedy Coulibaly, who was killed Friday along with the brothers behind a massacre at satirical newspaper Charlie Hebdo in nearly simultaneous raids by security forces. 
  
 "Today, Paris is the capital of the world," said French President Francois Hollande . "Our entire country will rise up toward something better." 
  
 Israel Prime Minister Benjamin Netanyahu and Palestinian President Mahmoud Abbas were among the leaders attending, as were top representatives of Russia and Ukraine. 
  
 Rallies were also planned in London, Madrid and New York — all attacked by al-Qaida-linked extremists — as well as Cairo, Sydney, Stockholm, Tokyo and elsewhere. 
  
 "We are all Charlie, we are all police, we are all Jews of France," Prime Minister Manuel Valls declared on Saturday, referring to the victims of the attacks that included employees at Charlie Hebdo, shoppers at a kosher grocery and three police officers. 
  
 The three days of terror began Wednesday when brothers Said and Cherif Kouachi stormed the newsroom of Charlie Hebdo, killing 12 people. Al-Qaida's branch in Yemen said it directed the attack by the masked gunmen to avenge the honor of the Prophet Muhammad, a frequent target of the weekly's satire. On Thursday, police said Coulibaly killed a policewoman on the outskirts of Paris and on Friday, the attackers converged. 
  
 While the Kouachi brothers holed up in a printing plant near Charles de Gaulle airport, Coulibaly seized hostages inside a kosher market. It all ended at dusk Friday with near-simultaneous raids at the printing plant and the market that left all three gunmen dead. Four hostages at the market were also killed. 
  
 Five people who were held in connection with the attacks were freed late Saturday, leaving no one in custody, according to the Paris prosecutor's office. The widow of the man who attacked the kosher market is still being sought and was last traced near the Turkey-Syrian border. 
  
 Early Sunday, police in Germany detained two men suspected of an arson attack against a newspaper that republished the Charlie Hebdo cartoons. No one was injured in that attack. 
  
 "The terrorists want two things: they want to scare us and they want to divide us. We must do the opposite. We must stand up and we must stay united," French Foreign Minister Laurent Fabius told French TV channel iTele on Sunday. 
  
 It was France's deadliest terrorist attack in decades, and the country remains on high alert while investigators determine whether the attackers were part of a larger extremist network. More than 5,500 police and soldiers were being deployed on Sunday across France, about half of them to protect the march. The others were guarding synagogues, mosques, schools and other sites around France. 
  
 "I hope that we will again be able to say we are happy to be Jews in France," said Haim Korsia, the chief rabbi in France, who planned to attend the rally. 
  
 "I hope that at the end of the day everyone is united. Everyone, Muslims, Jews, Christians, Buddhists," added Zakaria Moumni, who was at Republique early Sunday. "We are humans first of all. And nobody deserves to be murdered like that. Nobody." 
  
 At an international conference in India, U.S. Secretary of State John Kerry said the world stood with the people of France "not just in anger and in outrage, but in solidarity and commitment to the cause of confronting extremism and in the cause that extremists fear so much and that has always united our countries: freedom." 
  
 Posthumous video emerged Sunday of Coulibaly, who prosecutors said was newly linked by ballistics tests to a third shooting — the Wednesday attack on a jogger in a Paris suburb that left the 32-year-old man gravely injured. In the video, Coulibaly speaks fluent French and broken Arabic, pledging allegiance to the Islamic State group and detailing the terror operation he said was about to unfold. 
  
 The Kouachi brothers claimed the attacks were planned and financed by al-Qaida in Yemen.

A:
Leaders from across the globe descended on Paris today to stand by the side of French President Francois Hollande, as hordes of his countrymen crowded into the capital's iconic Republique Square to defiantly proclaim "Je Suis Charlie" in a rally to honor the 17 killed over the course of three horrifying days this week. "Paris is the capital of the world today," proclaimed Hollande before the start of the march, as per Sky News. "The whole country will stand up." He was joined by some 40 leaders ranging from David Cameron and Angela Merkel to Benjamin Netanyahu and Mahmoud Abbas; the United States sent outgoing AG Eric Holder. France's Interior Ministry says it's the biggest such demonstration in the nation's history, calling it "unprecedented" even in a nation known for its demonstrating; attendance estimates vary widely, with some French media putting the number at 3 million demonstrators. The Interior Ministry says the event was so heavily attended that it's impossible to tell. Similar rallies were planned in London, Madrid, and New York—which the AP notes have all been attacked by extremists linked to al-Qaeda—as well as Cairo, Sydney, Stockholm, Tokyo. The rally comes as French prosecutors today revealed that one of the gunmen had also been linked to the shooting of a female jogger; video also surfaced of Amedy Coulibaly pledging his allegiance to ISIS. The BBC has a live blog of the Paris rally here.
