Opposition parties in Liberia say they're pulling out of a recent presidential poll which they called "flawed" and say they won't accept the results.
A Saturday statement from eight opposition parties including those of the second- and third-place candidates say the electoral commission manipulated vote-counting in favor of President Ellen Johnson Sirleaf.
The statement also called for a Sunday rally but gave no details.
Sirleaf led late Friday with 45.4 percent of the vote, falling short of the majority needed to avoid a runoff, according to partial results.
The Harvard-educated Sirleaf faced 15 challengers on Tuesday. She is viewed abroad as a reformer and was awarded this year's Nobel Peace Prize for her role in stabilizing Liberia after a 14-year civil war.
