Haiti south '90% destroyed'

Nearly 900 people are known to have been killed by Hurricane Matthew in Haiti, with aid officials saying up to 90% of some areas have been destroyed.
Some of the hardest-hit towns are yet to be reached by land, and there are fears more bodies will be found.
Parts of Haiti's south had faced "complete destruction", aid workers told the BBC.
Hurricane Matthew is now heading towards South and North Carolina in the US, having battered Florida on Friday.
The US National Hurricane Center (NHC) has downgraded it to a Category 1 hurricane, with maximum sustained winds having decreased to 85mph (140km/h).
Storm surges and heavy rain are still expected to produce dangerous flooding in some coastal areas and Matthew will remain a hurricane until it begins moving away from the US coastline on Sunday, the NHC forecast.
