Haiti's President Rene Preval has been sworn in, becoming the nation's first elected leader in two years.
Mr. Preval took the oath of office Sunday in a ceremony in the capital, Port-au-Prince, which included representatives from the United States and several other countries.
Moments earlier, gunfire was reported inside a nearby penitentiary, where some prisoners were seen on the building's roof. No casualties were immediately reported in the apparent disturbance.
Mr. Preval was elected president in a February vote, about two years after President Jean-Bertrand Aristide was ousted.
He has vowed to work to reunify the Caribbean nation, which has suffered waves of violence since the 2004 uprising.
The 63-year-old former president will take over from an interim administration that is backed by United Nations peacekeepers from Brazil.
