Several hundred inmates who escaped from a prison in Haiti are believed to still be at large Sunday, after an attack on the national penitentiary left one guard dead.

Haitian officials say as many as 500 of the prison's 1,200 detainees may have escaped. It is unclear how many have been recaptured.

The prisoners fled after gunmen fired on the facility Saturday. The French news agency, AFP, quotes a government source as saying the raid was aimed at freeing drug traffickers.

Two high-ranking officials from the government of ousted Haitian President Jean Bertrand Aristide were among the prisoners who were quickly recaptured.

Haitian authorities say former Prime Minister Yvon Neptune and former Interior Minister Jocelerme Privert are back in custody. Both men have yet to be indicted. They are accused of violence against Aristide opponents.
