The FBI in Newark, New Jersey, said Thursday afternoon that it had received “credible information about a widespread threat to synagogues” in the state, according to a tweet from the office.   

  “At this time we ask that you take all safety measures to protect your community and facilities.  We will share more information as soon as possible.  Stay alert.  In case of emergency call the police,” the post said.   

  In a second tweet, the agency said it was taking a “precautionary measure” with this warning while “investigations are underway.”   

  New Jersey Gov. Phil Murphy said he is in contact with the FBI, the state’s Office of Homeland Security and Preparedness and the state’s attorney general.   

  “We are monitoring the situation closely and working with local law enforcement to ensure all houses of worship are protected,” Murphy tweeted.   

  In recent years, the US has seen an increase in anti-Semitic incidents, with 941 incidents in 2015 rising to 2,717 tracked in 2021 by the Anti-Defamation League.  On Thursday, the ADL said it was working with the FBI to address the credible threat and advised synagogues and Jewish organizations to “remain calm and on heightened alert.”   

  Just four years ago, a gunman stormed a synagogue in Pittsburgh, Pennsylvania, killing 11 people in the deadliest attack on Jews on US soil.   

  The FBI’s warning Thursday comes amid ongoing reports of anti-Jewish bigotry across the country, including multiple anti-Semitic messages displayed in public spaces in Jacksonville, Fla., over the weekend and a group of protesters hoisting banners over a Los Angeles freeway earlier in the day. October showing support for anti-Semitic comments made by Kanye West.  The photos also showed the group with their hands raised in what appeared to be the Nazi salute.  Los Angeles officials condemned the incident.   

  West had previously made a series of anti-Semitic outbursts, most notably on October 8 when he tweeted that he would “be dead in 3 [sic] About JEWS,” and also this, “You have played with me and tried to blackmail anyone who opposes your agenda,” without specifying which group he was addressing, according to Internet Archive Wayback Machine files obtained by CNN.   

  His tweet was removed and Twitter locked his account.  In an interview given after the controversial tweet, West told Piers Morgan he was sorry for the people he hurt, but said he didn’t regret making the remark.   

  CNN has reached out to the FBI for more information about his tweet.
