WASHINGTON, Nov. 7 (Xinhuanet) -- An unprecedented level of security will frame US President George W. Bush's second inauguration, with officials planning to use thousands of police from across the country, new screening technology for inaugural guests and a military contingent that could include a combat brigade of up to 4,000 troops.

    Security is always tight on Inauguration Day, but it will be magnified for the first inauguration since the Sept. 11, 2001, terrorist attacks, a Washington Post report said Sunday.

    Organizers are planning a traditional inauguration capped by a parade down Pennsylvania Avenue and the usual evening balls. Bush has yet to name his inauguration committee, which will oversee planning of the pageantry and festivities, but law enforcement agencies are in high gear.

    As tens of thousands of people are expected to come to Washington to watch the Jan. 20 swearing in, the city will be filled with military personnel, FBI agents, snipers on rooftops and scores of bomb-detecting dogs. The region's air defenses have been strengthened to prevent intruder aircraft, and sensors will be deployed throughout the area to detect biological, chemical or radiological material.

    "There will be far more security and more police than four years ago," Terrance W. Gainer, chief of the US Capitol Police, was quoted as saying. The Capitol Police is responsible for protecting the Capitol, where Bush will be swore in.

    Law enforcement authorities do not have specific information that terrorist groups are targeting the inauguration, but "the inaugural is a rich, symbolic, highly visible target," said Jim Rice, the FBI supervisory special agent who oversees the National Capital Response Squad.

    In suburban Northern Virginia, a temporary joint command centeris being set up in a federal facility, which will include representatives from other law enforcement agencies, such as the Washington D.C. police department, the US Park Police, the CapitolPolice and the FBI, the report said. Enditem
