Paris attacks: developments

Two Air France flights headed for Paris -- AF55 originating in Washington's Dulles Airport -- and AF65 from Los Angeles -- were diverted to Halifax, Nova Scotia, and Salt Lake City, respectively, following bomb threats, officials say. 

"Several law enforcement agencies are working to determine the nature of the threats which caused the aircraft to divert," FBI Special Agent Todd Palmer of the Salt Lake City division said.

It is unknown whether the same individual called in the two threats.

No U.S. military aircraft were scrambled in either of the reported Air France incidents, NORAD spokesman Preston Schlachter said.

The validity of the threat is not known at this time, but given the events in Paris Saturday, in which 129 people were killed, officials were taking extra precautions by diverting the flights. 

"Diversion of flights are the most draconian response to a bomb threat," CNN national security analyst Juliette Kayyem said. "I think right now we take this seriously until we hear some explanation to the validity of the bomb threat."

ORIGINAL STORY:

A Renault with Belgian plates and a cell phone containing a chilling message were among the focuses Tuesday in the sweeping multinational investigation into last week's terror attacks in Paris that killed 129 people. 

French President Francois Hollande says his country "is at war" after three teams of gun-wielding ISIS suicide bombers hit six busy locations. His military backed up the statement by pounding ISIS targets in Syria with airstrikes. Russia launched airstrikes and cruise missiles there. 

Meanwhile, a glimmer of hope for Syria's civil war, as America's top diplomat says a ceasefire could be on the horizon. 

Here's the key information at this stage:

The latest

-- NEW: As a growing number of U.S. governors said they don't want Syrian refugees in their states, President Barack Obama fired back. 

"I cannot think of a more potent recruitment tool for (ISIS) than some of the rhetoric that's been coming out of here during the course of this debate," Obama told reporters. Arguments that there should be a religious test before refugees are admitted or that only Syrian Christians should be allowed in are "offensive" and "contrary to American values," he said.

-- NEW: Obama accused Russian President Vladimir Putin of going after the wrong target in Syria, saying Russia has been more focused on propping up President Bashar al-Assad's regime than on fighting ISIS. "If, in fact, he shifts his focus and the focus of his military to what is the principle threat, which is (ISIS), then that is something that we very much want to see," Obama said.
