Three women have been killed and two injured in a stampede during a large Halloween Night party at an indoor arena in Madrid.

The women, aged between 18-25 years old suffered trauma injuries and heart failure after being crushed during a stampede, a health official said.

The crush came after a flare was reportedly set off within Madrid Arena in the west of the city, where thousands of people were partying.

The two injured women were in critical condition.

Halloween has recently become a popular festivity in Spain coinciding with the traditional feast of All Souls.
