A declassified memo from the National Intelligence Council warns that Iranian and Russian operatives could try to incite violence in America after all the ballots have been cast on Nov. 5. The memo says American spy agencies have already detected foreign efforts to stoke protests ahead of Election Day.

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.

Russia, China and Iran are intent on fanning divisive narratives to divide Americans ahead of the Nov. 5 U.S. elections and may consider fomenting violence after voters go to the polls, U.S. intelligence officials said on Tuesday.
