A bomb threat grounded Philly airport flights briefly Friday, but no explosives were found.

Flights at Philadelphia International Airport were briefly grounded Friday evening after a bomb threat prompted a U.S. FAA ground stop around 7 p.m. local time. The halt lasted about 30 minutes while authorities addressed a security concern involving one aircraft; no explosives were found, and the plane was cleared for departure. The incident follows similar unfounded threats at Reagan Washington National and LaGuardia airports earlier in November, all resolved without injuries or lasting disruptions, with the FBI confirming no credible threats in prior cases.
