Delhi intelligence agents have alerted Delhi police of a renewed threat from Muslim terrorists to attack at railway stations and the Delhi International Airport, where security has been beefed up. The threat of a fresh attack came from Deccan Mujahedeen, the same group that took responsibility for last week's siege on the Chabad House, two hotels, restaurants and other public places in Mumbai.

Police are working on information that the attack may come from a three-wheeled vehicle running on natural gas and which would cause more damage and injuries than a car bomb operated by gasoline.
