At least 169 people have died in a nightclub fire in Argentina.A further 375 were injured in what is being described as one of the country’s worst ever disasters. According to local media, thousands may have been inside the building in Buenos Aires, listening to a band, when the blaze broke out. It is thought to have been caused by a flare being fired into the club’s ceiling, sending burning debris onto the crowd and triggering a stampede. It was not immediately clear if fire exits and doors were unblocked. Parents rushed to the scene, desperate to find their sons and daughters amid the chaos. Children as young as 10 were among the victims.
