The Anti-Defamation League is reporting a 57 percent increase in anti-Semitic incidents in the U.S. last year, the highest tally that the Jewish civil rights group has counted in more than two decades, according to data it released Tuesday.

The New York City-based organization found 1,986 anti-Semitic incidents last year, up from 1,267 in 2016. That’s the highest total since 1994 and the largest single-year increase since the group began collecting this data in 1979.

The ADL said the sharp rise includes 952 vandalism incidents, an increase of 86 percent from 2016. The group also counted 1,015 incidents of harassment, a 41 percent increase from 2016.
