Helene is deadliest mainland US hurricane since Katrina as toll hits 200

The death toll from Hurricane Helene has risen to 200 as rescuers continue to search for survivors from the storm that tore across the US south-east.

More than half of the deaths were in North Carolina, where entire communities were uprooted and devastated by the deadliest mainland storm since Katrina in 2005.

Hundreds of people are still missing and nearly a million homes are without power nearly a week after Helene made landfall.
