At least 45 people were burned or trampled to death when giant exhibition tents caught fire at a trade fair in north India, authorities said. Another 160 were hospitalized. The blaze occurred at a consumer electronics show in the dusty rural town of Meerut, about 400 kilometers from the city of Lucknow. Witnesses described a horrific scene, with screaming injured people, three enormous tents destroyed, and rescuers pulling out corpse after corpse. At least 22 ambulances ferried the injured to hospitals in the area, officials said.
