Paris massacre: At least 128 killed in gunfire and blasts, French officials say-

Those Americans in France needing assistance should call 001-202-501-4444. Americans concerned about loved ones in Paris should call 1-888-407-4747. 

Paris Prosecutor spokeswoman Agnès Thibault-Lecuivre said eight extremists are dead after attacks. Seven of them were killed in suicide bombings.

• U.S. President Barack Obama spoke with French President Francois Hollande to offer condolences and assistance in the investigation, the White House said. Earlier, Obama said, "This is an attack not just on Paris, not just on the people on France, but an attack on all humanity and the universal values we share." He called the attacks an "outrageous attempt to terrorize innocent civilians."

• A total of six locations were attacked in and just outside the capital, Paris prosecutor François Molins told reporters Saturday.

• Five suspected attackers have been "neutralized," said Molins. It was unclear whether that term meant the terrorists were dead.

• A witness tells Radio France that attackers inside the Bataclan concert hall entered firing rifles and shouting "Allah akbar."

• At least 128 people were killed in the Paris and Saint-Denis shootings and bombings, French officials said. Saint-Denis is home to the national stadium where the soccer match was being played.

• The worst carnage occurred at Bataclan, with at least 80 left dead. A journalist who was at a rock concert there escaped and told CNN: "We lied down on the floor not to get hurt. It was a huge panic. The terrorists shot at us for 10 to 15 minutes. It was a bloodbath." Julien Pearce didn't hear the attackers speak, but he said one friend who escaped heard them talk about Iraq and Syria. Later, he said the men were speaking French. Two men dressed in black started shooting and after wounded people fell to the floor, the gunmen shot them again, execution-style, he said.

• CNN affiliate BFMTV, citing French officials, said some gunmen were still at large.

• Charlotte Brehaut and a friend were dining in Le Petit Cambodge, a Cambodian restaurant, when the shooting started from the street, she told CNN. "All of a sudden we heard huge gunshots and glass coming through the windows. We ducked with the other diners," she said. She grabbed the arm of a woman on the floor. The woman didn't respond. The woman was shot in the chest and there was blood all around her. At least 14 people were killed in Le Petit Cambodge, authorities said.

• Four attackers were killed, including three who were wearing explosives belts, at Bataclan during the police raid, Paris police spokesman Michel Cadot told France Info radio.

• There is great alarm over the apparent methodology and likely planning that would have been needed to pull off such a series of attacks, one U.S. counterterrorism official told CNN. The attacks resembled tactics that have been used by a number of terror groups -- including al Qaeda's focus on mass casualties and visibility, and the small, tactical nature of attacks that are more the hallmark of ISIS and its acolytes. It is still not clear who is responsible.

• U.S. citizens in Paris who are safe are being asked by the State Department to call their families. Those Americans in France needing assistance should call 001-202-501-4444. Americans concerned about loved ones in Paris should call 1-888-407-4747. An official told CNN the hotline was flooded with calls.
