Following the presidential election, groups monitoring the election gave it a dismal assessment. Chief European Union observer Max van den Berg reported that the handling of the polls had "fallen far short" of basic international standards, and that "the process cannot be considered to be credible." A spokesman for the United States Department of State said it was "deeply troubled" by election polls, calling them "flawed", and said it hoped the political parties would resolve any differences over the election through peaceful, constitutional means.
