Iranians voted in a second round of parliamentary elections on Friday, with allies of reformist President Hassan Rouhani seeking to wrest more seats from hardliners.
Rouhani's moderate and centrist allies made big gains in elections on Feb. 26 for parliament and a clerical body that will elect the next Supreme Leader, but they failed to win a majority of the 290-member assembly.
Interior Minister Abdolreza Rahmani Fazli, speaking on Iranian state television, said people would vote on 68 undecided seats in constituencies where candidates failed to get 25 percent of votes cast in the first round.
Results would be announced by Sunday, he said.
"We are trying to announce the final result as soon as possible. Even maybe on Saturday or Sunday," he said.
