PORT-AU-PRINCE, HAITI - Rene Preval has been sworn in as president of Haiti.
He took the oath of office before some 300 legislators and foreign dignitaries, including Florida Gov. Jeb Bush.

Preval replaces a U.S.-backed interim government that was appointed to lead the Caribbean nation after former President Jean-Bertrand Aristide fled into exile in 2004.

Preval ruled Haiti from 1996 to 2001. He's the only president in Haiti's history to finish a five-year term.

He faces big challenges, including a wrecked economy and a corrupt state bureaucracy.
Before the inauguration, inmates rioted at Haiti's main prison about a half-mile away. Gunfire could be heard from inside the prison and about 100 inmates massed on the roof.

Haitian police and U.N. peacekeeping troops surrounded the prison and restored order.
