ST. CLOUD - The FBI and Homeland Security have issued a nationwide warning about Al Qaeda threats to small airplanes, as we approach the 10th anniversary of the 2001 terrorist attacks.

St. Cloud Regional Airport Director Bill Towle says it will be business as usual this week at the airport.

Authorities say there is no specific or credible threat.  But they have stepped up security across the country as a precaution.  As recently as earlier this year, Al Qaeda was considering ways to attack airplanes again.
