Amorim's suggestion came amid renewed violence in Haiti as supporters of presidential hopeful Rene Preval demanded he be declared the country's new leader.
At least one person was killed Monday during clashes between Preval supporters and U.N. peacekeepers.
Ballot counting for last week's election continues, however. In the days following last Tuesday's vote it appeared Preval had garnered nearly 60 percent of the vote, but as the count continued, his lead began to slip.
It now appears that Preval, a former president from 1995-2000, did not win the necessary votes -- more than 50 percent -- needed to avoid a runoff election, and that a runoff will be scheduled for next month.
