Terrorists could decide to launch attacks during the holiday season but the United States has no evidence any plots are being planned, according to a federal law enforcement intelligence bulletin issued Wednesday. The US Department of Homeland Security and FBI joint notice to local law enforcement partners says federal officials \"are not aware of any credible threats to the Homeland specifically timed to coincide with the 2011 holiday season.\" The CNN obtained a copy of the document, which goes on to say intelligence received in the last year suggests \"terrorists recognize that the large gatherings occurring during the holiday season provide an opportunity for mass casualty attacks.\" The warning came days after an American man descended from the Dominican Republic, who authorities say is sympathetic toward al-Qaida, has been arrested for an alleged bomb plot in New York.
