Former US president Bill Clinton (L), who heads UN efforts to rebuild Haiti, shakes hands with CNN reporter Anderson Cooper after he received a medal during a remembrance ceremony on July 12 2010 on the grounds of the destroyed presidential palace in Port-au-Prince, on the six-month anniversary of the devastating January 12 earthquake. Haitians marked the anniversary, mourning the hundreds of thousands killed six months ago in a massive earthquake and eyeing a precarious future amid the slow trickle of aid. In the ruins of the presidential palace toppled by the January 12 quake which measured 7.0 in magnitude, international supporters joined Preval and other leaders in a poignant remembrance ceremony.
