Some 1,500 extra soldiers have been mobilized to guard French facilities and schools and universities are closed because of the country's deadliest attacks in decades.

Many French schools are normally open on Saturdays, but the French government ordered them shuttered as part of emergency security measures.

Soldiers were deployed at key sites around Paris, including Parliament buildings and religious sites.

The government has also reimposed border controls that were abandoned as part of Europe's free-travel zone. Border and customs officers will check people, baggage and vehicles entering and leaving France by road, train, sea or plane, said customs official Melanie Lacuire.

Iranian President Hassan Rouhani has canceled trips to France and Italy after terror attacks in Paris that killed over 120 people.

The state-run IRNA news agency quoted Rouhani as saying Saturday that Iran "itself has been a victim of the scourge of terrorism" and the fight against terrorism must go on. It did not elaborate why he canceled the visit, but authorities said the trip would be rescheduled.

Rouhani was due in days to travel to France and Italy. France was one of the world powers involved in recent negotiations with the Islamic Republic over its contested nuclear program.

Hossein Jaber Ansari, a Foreign Ministry spokesman, also was quoted by IRNA as saying: "Those terrorist groups that committed the Paris crimes do not believe in ethical principles and they are not loyal to any type of divine religions — including Islam."

Friends and relatives are using social media to search for loved ones feared to have been at the sites of the Paris attacks.

"We are looking for Marie, who was at the Bataclan, we have no news from her. If you see her, please contact me #Bataclan", reads one tweet from @Photographys, posted with a photo.

"If you have news of Christophe aka @MokeComputer he was at Bataclan tonight and we need to hear from him," tweets a user named @Lorelei_Jade.

Facebook also offered its "Safety Check" feature to allow users who listed to mark themselves as safe if they listed Paris as their location.

Earlier in the evening, Parisians used the hashtag #portesouvertes, or "open doors," to offer a place to stay for people who were evacuated from the sites of the attacks. In the U.S., some used the hashtag #strandedinUS to offer shelter for people who were unable to travel back to France.

He called on the French to remain united. "We will lead the fight. We will be merciless."

The California congressman says investigators would scour any electronic devices that they managed to recover from the gunmen. He says it is possible but not definite that some of the attackers would be known to French law enforcement — as was the case with the Charlie Hebdo attack in January.
