The Air India flight fell from the sky on Thursday and killed at least 270 people in Gujarat state, officials said Saturday.

The death toll in the deadly Air India plane crash rose to 270 on Saturday, with families increasingly getting upset due to delays in handing over bodies which were badly charred in the tragedy in the western Indian city of Ahmedabad.
