Pyrotechnics have often been the cause of deadly fires in nightclubs, including the one at the Colectiv club in Bucharest, Romania, in 2015 in which 64 people died.

SKOPJE: A fire that broke out at a nightclub in North Macedonia where more than a thousand people had gathered for a concert killed at least 51 people, the country's interior minister said on Sunday (Mar 16).

Fire ripped through a packed nightclub early on Sunday in the North Macedonian town of Kocani, killing 59 people and injuring more than 150, officials said, after sparks ignited the roof above a live band.
