Terror in US food store as gunman opens fire
US police in Philadelphia are trying to find a man who fired into an Asian food store and wounded three people on Tuesday night.
Investigators have released a surveillance video of the crime on YouTube.
The video, which features images from inside the store as well as from a camera outside, shows a man in grey walking up to the store and firing a shot through the glass front door.
Several young men are seen scrambling to hold the door shut from inside.
