Geneva: The International Federation of the Red Cross estimates that up to 3 million people have been affected by a powerful earthquake that caused massive destruction in the Haitian capital.
Spokesman Paul Conneally says the fact that the quake occurred very close to Port-au-Prince was "not a good indicator"
He says Haiti is one of the poorest countries in the northern hemisphere and is ill-prepared to handle a major disaster.
Conneally told The Associated Press on Wednesday that it would take 24-48 hours before a clear picture emerges of the scale of the destruction.
Meanwhile, international aid groups including the Red Cross are gearing up for a major relief effort in Haiti focused on rescuing survivors and setting up field hospitals for the wounded.
