FBI, State Dept. issue warnings after France terror attacks

The Federal Bureau of Investigation on Friday sent out an intelligence bulletin reminding U.S. law enforcement partners to be aware of the potential for homeland attacks carried out by sympathizers or followers of radical Islamic groups, CBS News correspondent Bob Orr reports.

The FBI alert primarily features an update and analysis of the recent attacks in Paris.

Also Friday, the State Department issued a "worldwide caution" regarding "the continuing threat of terrorist actions and violence against U.S. citizens and interests."

The travel warning says attacks against Americans are becoming increasingly prevalent. It also cites an increased risk of reprisals against U.S. and Western targets for the U.S.-led intervention against Islamic State militants in Syria and Iraq.

Said and Cherif Kouachi, the brothers accused of attacking a Paris newspaper on Wednesday, were killed Friday after an all-day hostage siege at a printing plant northeast of Paris.

Their apparent associate, Amedi Coulibaly, took more than a dozen hostages at a kosher grocery in Paris and held them for several hours before he was killed in a nearly simultaneous raid. Four hostages also died.

In a statement, the FBI said: "The Bulletin was sent out as part of our continuous dialogue with the law enforcement and Intelligence community in an effort to provide an assessment of the current threat landscape and to share information relative to threat indicators and possible security measurement considerations. We urge the public to remain vigilant and report suspicious activity to law enforcement."

Officials say there is no credible information suggesting that any U.S. attack is imminent, but the bulletin says it is important for police and the public to remain vigilant.

Sources say U.S. law enforcement and intelligence analysis have found nothing connecting the three dead French terror suspects to any threat or co-conspirators in the U.S.

Orr reported that the Kouachi brothers had been on the U.S. no-fly list.

The State Department warning also cited December's hostage standoff at a Sydney cafe and the killing of a soldier near Canada's parliament in October.
