Mum Films Children Singing In Back Of Car Before Crash

A distressing video showing a mum using her phone to film her children singing in the back seat of their car before they crash has been posted online.

The film shows the girl and boy, who look between three and five years old, strapped into their booster seats, waving their arms in the air, before the car crashes with a horrendous bang and then fills with smoke.

It isn't clear whether the clip is authentic or is intended as a warning to people not to film and drive.

After the crash the mother curses: "Oh s**t."

One of the children then asks: "What happened?"

According to the video, posted on LiveLeak, none of the occupants were harmed.
