UN Secretary -General back in Haiti

The United Nations Secretary-General, Ban Ki-moon, is now on his second visit to Haiti since the country was struck by a huge earthquake in January.



Mr. Ban is assessing for himself the challenges facing the relief effort.



He says the visit will give him a much clearer picture of the situation ahead of an aid donors\' conference at the end of the month.



Hundreds of thousands of people in Haiti are still living without adequate shelter and sanitation, as the rainy season approaches.
