Iraq’s prime minister said on Tuesday there were “dangerous violations” in the May 12 parliamentary election and banned members of the election commission from traveling, a move that could hinder the delicate process of forming a new government, Reuters reported.

The election was won by a bloc led by cleric Moqtada al-Sadr, a long-time adversary of the United States who also opposes Iran’s sway in Iraq.

Haider al-Abadi told a news conference that a report presented to the government recommended a partial manual recount of the vote and the cancellation of results from overseas and displaced voters.
