Three women were crushed to death in a stampede caused by a firework at a Halloween party in Madrid.

The incident happened at the Madrid Arena where thousands of revellers had gathered for the party.

Panic erupted when someone lit a flare or firecracker in a corridor of the arena.

Two women were killed at the venue and a third died in hospital. Two other women are in critical condition.

Halloween parties are popular in Spain where the traditional All Saints' Day festival is a public holiday marked by people putting flowers on the graves of their relatives.
