NYPD's Kelly: Terror threat still alive

Airports across the world are stepping up security on the first anniversary of the death of Osama bin Laden as new intelligence hints at future al Qaeda threats and authorities tell ABC News they fear the group may soon try to explode U.S.-bound aircraft with explosives hidden inside the bodies of terrorists.

“Al Qaeda and the terrorist threat is very much alive,” New York City Police Department Commissioner Ray Kelly tells “Starting Point” anchor Soledad O’Brien this morning.

Al Qaeda’s future plans detailed in documents German officials discovered encoded on a memory disk belonging to a suspected al Qaeda operative arrested in Berlin last year include hijacking a cruise ship, dressing the passengers in orange jump suits - to mimic Guantanamo Bay prisoners - and posting the “executions” on an al Qaeda web site.

The intelligence community in New York has also been looking into the idea of implanted body bombs that could possible escape airport-scanner detection for a while, Kelly said. “Obviously we have to be concerned about it.”

Kelly says anti-terrorism efforts in New York are focused closely on nuclear threats. “A nuclear event is the thing that concerns us the most.”

Watch Kelly talk to Soledad about New York’s One World Trade Center and the fight to prevent terrorism in the city he calls “the number one target in the United States.”
