Michel "Sweet Micky" Martelly, a pop star known for his bad-boy antics on stage, became earthquake-devastated Haiti's new president and urged his countrymen to set aside their divisions and raise the nation from rubble.

Musician Michel "Sweet Micky" Martelly scored a come-from-behind victory in Haiti's presidential run-off, according to preliminary results from last month's election showing he easily defeated a former first lady for the leadership of a country facing enormous challenges.

Furious supporters of eliminated candidates set fires and put up barricades in the streets of Haiti's capital after officials announced that government protege Jude Celestin and former first lady Mirlande Manigat would advance to a second round run-off in presidential elections.
