Al-Qaida may be working to attack US

WASHINGTON Air Force Gen. Gene Renuart, who is chief of the U.S. Northern Command, told reporters he has not seen any direct threats tied to the U.S. presidential elections. But he says it would be imprudent to think that such threats are not there.

While he believes that U.S. authorities have thwarted attacks on a number of occasions, he says terrorist cells may be trying harder than ever to plot high-impact events.
