Here is the latest:
• How many people died?
Most of the 127 confirmed fatalities resulted from the mass shooting at a rock concert in the center of the city around 9 p.m. local time. Other deaths came after suicide bombings and shootings around the same time in five other locations, including restaurants and a soccer stadium.
Nearly 300 people were wounded, at least 80 of them in critical condition, Paris hospitals say. Hospitals are full today, and people are lined up to give blood.
It is the worst terrorist attack in Europe in 11 years, since the 2004 coordinated bombings of commuter trains in Madrid killed 191 and wounded 1,800.
Seven of the Paris attackers died in suicide bombings, and an eighth was shot by police. Officials say accomplices may still be at large.
• Was the Islamic State responsible?
Secretary of State John Kerry, in Vienna for talks with other foreign ministers over the Syria conflict, condemned the attacks but did not name the militant group, also called ISIS, ISIL or Daesh, an Arabic acronym.
American officials in Washington on Saturday did not dispute the French president’s conclusion.
Still, the authorities have not yet indicated whether they know the identities of the eight attackers, including whether they were French.
We also don’t know what intelligence led President François Hollande to blame the group, or whether the attackers received training, weapons or bomb material from the Islamic State.
• What is Paris like today?
The capital is under a heavy police presence, and checks at France’s borders have been reinstated. Air travel continues but with significant security-related delays.
Public protests — a constitutional right in France — are prohibited in Paris and some of the surrounding departments until Thursday.
Events (tonight’s U2 concert in Paris, a large photography exhibit) are canceled. Schools, cultural places and other venues (the Eiffel Tower, movie theaters, Disneyland Paris, department stores) are closed.
The French president declared three days of mourning, and officials are advising Parisians to stay home. A memorial Mass is set for the Cathedral of Notre-Dame on Sunday evening.
• Other recent terror activity?
On Thursday, more than 40 people were killed in Beirut, Lebanon, in a bombing that targeted Iran’s Hezbollah allies. Earlier this month, more than 200 people died in the explosion of a Russian charter jet over Egypt.
Islamic State claimed responsibility for both, and, now with Paris, the events suggest that the regional war has transformed into a global one.
In January, Paris suffered another massacre, when 17 people were killed at the French satirical weekly Charlie Hebdo and in related attacks around the French capital.
• Why Paris?
The Islamic State claimed the attacks were a response to France’s campaign against its fighters and insults against Islam’s prophet. The group warned that France would remain one of its top targets.
Far-right politicians were already stoking xenophobic sentiment, especially Marine Le Pen, the leader of the National Front party, who vowed to close borders. Regional elections are Dec. 16.
Bomb threats in Paris have become almost routine: Friday had begun with one at the German soccer team’s hotel and one at the Gare de Lyon train station.
• What’s next?
Angela Merkel, chancellor of Germany, and David Cameron, prime minister of Britain, separately held crisis talks with their ministers today.
The French president is sending his foreign minister to Turkey on Sunday for the Group of 20 summit meeting in his stead.
Terrorism — and perhaps immigration — has now become the main topic for tonight’s debate of the candidates for the Democratic nomination for U.S. president.
On social media, people are using the hashtags #prayforparis, #parisattacks and #MuslimsAreNotTerrorists. Facebook turned on its “Safety Check” tool so people could let friends and family know they were safe.
The France 24 television channel has live online video coverage in English.
