New York City officials have agreed to pay up to $657.5m (£437m) to thousands of rescue and clean-up workers after 9/11.

The settlement would compensate more than 10,000 plaintiffs who say they were made sick by dust at the Ground Zero site of the attacks.

At least 95% of the plaintiffs must approve the deal for it to take effect.

The money would come from a federally financed insurance fund of almost $1bn that the city controls.

The toxic cloud from the collapsed World Trade Center towers contained particles of asbestos, lead, glass and cement.
