Three teenagers shot dead after Facebook argument which began in school spiralled out of control

Three teenagers were shot dead in an ambush following an argument which began in school and continued on Facebook.

Seven teenage boys packed into a Toyoto Corolla and went looking for a planned fight with three brothers involved in the argument.

The group drove up to a house in Philadelphia, U.S, but it is believed a man in a grey hoodie came out of the house and approached them.

Concerned by this, the group drove to the back of the house but police said the same man came out of the door and fired 12 shots at point-blank range.

Three members of the group died.
