Following reports of exploding handsets worldwide, the US Consumer Product Safety Commission (CPSC) has advised all Samsung Galaxy Note7 owners to "power them down and stop charging or using the device."

The CPSC has said that it is working with Samsung to "formally announce an official recall of the devices, as soon as possible".

A statement released by the Commission says: "This consumer warning is based on recent reports involving lithium-ion batteries in certain Note7 devices that have resulted in fires.

"These incidents have occurred while charging and during normal use, which has led us to call for consumers to power down their Note7s."
