U.S. Federal officials have credible new intelligence of plans for another al Qaeda attack on the U.S., NBC reported.
Officials say they have information that al Qaeda in Yemen is planning another attack but declined to give further details.
However, they have described the information as “credible” and are considering whether to step up security measures.
One official has said the news is not surprising, as they had expected further attacks following the failed Christmas Day airliner bombing plot.
