At least 43 people were killed Sunday in a devastating fire that ripped through a bag factory in the congested old quarter of the Indian capital New Delhi, with survivors describing the screams of workers trapped inside. The blaze was the worst in Delhi since 59 movie-goers died in a cinema in 1997. The cause of the blaze is not yet known, but the city's poor planning and lax enforcement of building and safety codes have often been blamed for such deadly incidents.
