The Department of Homeland Security and the FBI today briefed building owners in the United States "regarding the tactics terrorists used in the attacks last week in Mumbai, India." The five-page "Intelligence and Analysis Note" said that the DHS and FBI "have no credible or specific information that terrorists are planning operations against public buildings in the United States." But it is important for building owners and operators "to be aware of potential attack tactics," the note said.
The DHS and FBI gathered details of the attack from open reports and "interrogations of a captured terrorist," the note said. It ticked off many of the now well-reported details, including the use of boats to gain unfettered access to Mumbai and the "synchronized and coordinated" nature of the massacre.
But it also included some lesser known facts about the terrorist assault. The note said, for example, that the "attack planners used publicly available commercial imagery to plan the attack," such as satellite mapping of Mumbai. It added that while "at least 10 operatives" circumvented security by entering Mumbai from the sea, "others arrived in the city as many as four days prior to the attack."
The note said that the terrorists "were clean shaven and dressed in Western street clothing, possibly to blend in with the population" and that they entered the Taj Mahal Hotel through back alleys to surprise security guards. Once inside, they "moved continuously throughout the facilities." The constant movement "made it difficult for authorities to identify locations of attackers and hostages," the FBI and DHS wrote.
Similarities to jihadist training tape?
The unclassified note also pointed out similarities in the attack and the terror tactics discussed on a jihadist training tape that European authorities seized earlier this year. That compact-disk audio recording, made about five years ago by a now-deceased senior al-Qaida operative, provided instruction to potential suicide terrorists on seizing publicly accessible buildings.
On the tape, the al-Qaida leader recommended assembling a team of 12 individuals, each armed with an assault rifle and grenade and carrying approximately 20 kilograms of explosives. According to a government translation of the tape, it said, "The attackers are to storm the building, seal off escape and access points, and occupy it long enough to set and detonate their explosive packages."
Today's joint DHS/ FBI note said the government does not have any information indicating that the Mumbai terrorists used the al-Qaida training tape to prepare for the attack. "In addition, we have no information indicating that the group received training from al-Qaida," it said. But it pointed out that some of the tactics were "similar."
Since 9-11, DHS and the FBI have issued hundreds of similar warnings and bulletins to law-enforcement officials and private businesses, cautioning them about potential terrorist attacks.
