An exploding lithium-ion camera battery caused a panic at the Orlando International Airport on Friday, resulting in 24 flight cancellations as well as temporary chaos as a terminal was evacuated. Witnesses say the exploding battery made a sound similar to a gunshot, prompting people to flee the area.

Though frightening, the situation proved mostly harmless as officials discovered the source of the sound: a camera battery that had exploded inside of a traveler's bag, which began smoking as a result. Orlando Police have since posted tweets advising the public that no shots were fired in the airport, but instead that "a lithium battery in a camera exploded in a bag ... the bag was smoldering." No one was hurt in the incident.

The incident follows a recent recommendation by the FAA that airlines ban passengers from checking devices with lithium-ion batteries in bags due to their volatility and the fire risk they pose, instead suggesting they pack them in their carry-on luggage.
