DHS Ramps Up Holiday Terror Alert | Bulletin Based on Persistent “Evolving” Threat.

Holiday Terror Warning Cites Car Bombs and Small Arms Attack

Federal law enforcement terror bulletins have become as much a part of the holiday season in the past decade as egg nog and department store Santas.

But this year, which ends amid a heightened concern over terror, is a little different. A Department of Homeland Security bulletin sent to law enforcement nationwide Thursday says that federal authorities worry terrorists will try to rattle Americans by attacking during the holidays, and lists concerns including car bombs, trucks ramming crowds and a Mumbai-style small arms attack.

“We are concerned these terrorists may seek to exploit the likely significant psychological impact of an attack targeting mass gatherings in large metropolitan areas during the 2010 holiday season, which has symbolic importance to many in the United States,” The “Security Awareness for the Holiday Season” bulletin states.

The bulletin cites no specific threats for Christmas and New Year’s, but makes clear that this year’s enhanced concern is based on a persistent, evolving threat. The past 12 months brought multiple attempted attacks on U.S. targets, including the attempted Christmas Day underwear bombing of Northwest 253, Faisal Shahzad’s failed Times Square car bomb, the “printer bomb” cargo plane plot and a number of alleged would-be bombers caught in stings in Oregon and elsewhere.
