Perdue said Friday state government is keeping a close eye on activities surrounding federal agents tracking a credible but unconfirmed tip that al-Qaida has plans to set off a car bomb in New York City or Washington around this weekend's anniversary of the 2001 attacks.
Crime Control and Public Safety Secretary Reuben Young said he was briefed by the Department of Homeland Security and urged people to alert law enforcement if they see something suspicious.
"The good thing about North Carolina is that we're always vigilant and we're always prepared, and Secretary Young and the state is on alert we remain on alert we are not afraid. People need to understand go ahead and be vigilant and move forward with their day to day lives - very cognizant of all that's going on," said Perdue.
Perdue spoke after signing a proclamation at a ceremony in downtown Raleigh designating Sunday as a day of remembrance and service and next week as a time of appreciation for first responders.
