Evidence found in the failed London and Glasgow bombings indicates that al Qaeda terrorists and perhaps operational cells are functioning inside the United States. The news has surfaced at the same time an American-born al Qaeda spokesman, Adam Gadahn, has threatened to attack U.S. targets in the homeland and abroad.

Following the bombing attempts in London and Glasgow over the July 1 weekend, investigators have established that the perpetrators’ e-mail chains used to communicate with al Qaeda operatives in Europe also included e-mail addresses belonging to Americans, according to the New York Sun.

At one point, two of the British plotters attempted to travel to the U.S. for an unknown purpose.

“Because of the London and Glasgow plot, we now know communications have been made from al Qaeda to operatives in the United States,” a counterterrorism official told the newspaper.

The source added that no specific names, targets or timelines were uncovered regarding an imminent attack on the American homeland.

“I believe there are cells in the United States, or at least people who aspire to create cells in the United States,” Northern Command Air Force General Victor Renuart said. “To assume that there are not those cells is naive, and so we have to take that threat seriously.” Northern Command is the operational theater including North America.

Secretary of Homeland Security Michael Chertoff has said he has a “gut feeling” about an increased risk of attack.

Al Qaeda, which was responsible for the horror of September 11, released a video this weekend threatening to strike American embassies. Adam Gadahn, a California native and now an al Qaeda member, appears in the video, stating, “We shall continue to target you, at home and abroad, just as you target us, at home and abroad ….”

A June 9 video depicting a Taliban terrorist “graduation” ceremony depicts men and boys placed in groups responsible for attacks in specific Western countries, including the United States and Britain. The Sun attributes the video to al Qaeda.

Terrorism continues to spread throughout the West in spite of the war on terror, and many believe it is only a matter of time before the next cataclysmic attack takes thousands of lives and smashes the economy.
