Russia and Iran may try to encourage violent protests in the U.S. after next month’s election, senior intelligence officials warned Tuesday, citing two recent examples of foreign intelligence agencies seeking to sow discord ahead of the vote.

Foreign powers are likely to aim to promote protests disputing the presidential-election results, officials said.

Russia, Iran and China are intent on fanning divisive narratives to divide Americans ahead of the Nov. 5 U.S. elections, an American intelligence official said on Tuesday, although they are unlikely to be able to manipulate the contests at a scale that would affect the outcome of the presidential race.

Russia and Iran may seek to foment violent protests inside the US in the days and weeks after the Nov. 5 election as voting results are being tabulated and certified, US intelligence agencies warned on Tuesday.
