COLLEGE PARK, Md. (AP) — At least 12 white supremacists have been arrested on allegations of plotting, threatening or carrying out anti-Semitic attacks in the U.S. since the massacre at a Pittsburgh synagogue nearly one year ago, a Jewish civil rights group reported Sunday.

The Anti-Defamation League also counted at least 50 incidents in which white supremacists are accused of targeting Jewish institutions’ property since a gunman killed 11 worshippers at the Tree of Life synagogue on Oct. 27, 2018. Those incidents include 12 cases of vandalism involving white supremacist symbols and 35 cases in which white supremacist propaganda was distributed.

The ADL said its nationwide count of anti-Semitic incidents remains near record levels. It has counted 780 anti-Semitic incidents in the first six months of 2019, compared to 785 incidents during the same period in 2018.

The ADL’s tally of 12 arrests for white supremacist plots, threats and attacks against Jewish institutions includes the April 2019 capture of John T. Earnest, who is charged with killing one person and wounding three others in a shooting at a synagogue in Poway, California.
