The number of hate and bias incidents reported across the United States spiked in the 10 days following Donald Trump's presidential election victory, according a report released on Tuesday by a civil rights advocacy group.

The report, by the Southern Poverty Law Center, documents 867 incidents ranging from assaults to threatening graffiti messages, based on incidents reported to the group or by news media.

That is a major increase from the normal rate of hate incidents reported in the United States, said Richard Cohen, the group's president.
