A United Nations Security Council delegation is to visit Haiti next week to evaluate UN contributions to development and security, Costa Rican Ambassador Jorge Urdina said Friday according to dpa. The visit by the nine-member delegation led by Urdina, which is to start Wednesday, follows a first-hand assessment by UN Secretary General Ban Ki-moon and former US president Bill Clinton of conditions in the one of the poorest nations in the Caribbean. Ban and Clinton will arrive in Port-au-Prince Monday for discussions with the Haiti government on issues ranging from economic recovery to security.
