CHICAGO (CBS) — There is renewed concern for travelers in and out of Chicago’s O’Hare and Midway airports about the potential for terrorists to set off a shoe bomb.
The Department of Homeland Security has in the last 12 hours put out an advisory to airlines to be aware of new “chatter” about explosives in shoes.
While not a new threat, there is a renewed concern terrorists attempting to carry explosives in shoes, CBS News reports.
Officials tell CBS News that no direct threat has been made, but the chatter was enough to cause federal security officials to issue a warning to airlines and security officials worldwide for U.S.-bound flights.
Increased security is likely in terms of more pat downs and shoe checks.
DHS says the alert was put out under an “abundance of caution.”
Richard Reid attempted to detonate explosives packed into his shoes while on a flight from Paris to Miami three months after the 9/11 attacks.
On Christmas Day 2009 on a flight to Detroit, a Nigerian man tried to set off explosives hidden in his underwear.
