(Video) Explosion aboard Shanghai-bound flight forces emergency landing in HK

A Royal Air Philippines flight from Boracay to Shanghai had to make an emergency landing at Hong Kong International Airport last night after a power bank exploded and smoke filled the cabin. No injuries were reported.

An online video shows moments just after the explosion aboard flight RW602 on Monday. Smoke was seen billowing from the front part of the cabin, gradually filling the air. 

Some passengers were terrified and moved to the back of the cabin to avoid inhaling the smoke.

The captain then made an emergency landing in Hong Kong. The incident was cleaned up after about an hour, and passengers proceeded with the flight and landed in Shanghai at around 12.30 am on Tuesday - a 3-hour delay.

It was not known how many passengers were on board when the incident happened.

It remains unclear what caused the portable battery charger, which is banned from being placed in check-in baggage, to explode.
