Charities concerned as Tropical Storm Isaac hits Haiti camps
High winds and driving rain are lashing the coast of Haiti as Tropical Storm Isaac moves closer to the shore.
The centre of the storm was last reported as being about 100km from the Haitian capital, Port-au-Prince.
Forecasters say Isaac could cause life-threatening flash floods and mudslides.
Some 400,000 Haitians are still living in tents in makeshift camps after the deadly earthquake of 2010.
An official from the charity Operation Blessing International described how the storm is threatening them.
