Haitian police say at least five more bodies have been found in a marketplace burned down by gunmen.
The discovery was made Wednesday, a day after two other people were killed when fire ripped through the marketplace in the capital, Port-au-Prince.
The attackers were alleged to be supporters of former President Jean-Bertrand Aristide.
Wednesday's discovery followed news that a French diplomat had been slain while driving through Port-au-Prince.
The French Embassy in Haiti said Paul-Henri Mourral, the honorary French consul to the northern city of Cap-Haitian, was shot late Tuesday by gunmen who then stole his vehicle.
The French Foreign Ministry condemned the killing and demanded the Haitian government bring the killers to justice.
U.S. Ambassador to Haiti James Foley has called the security situation "serious and grave."
