JEWISH community centres across the US have been targeted with hoax bomb threats following a wave of attacks on cemeteries.

Eleven Jewish community centres across the country received telephoned bomb threats on Tuesday, according to the JCC Association of North America.

As with three waves of similar phone calls in January, the new threats proved to be hoaxes, the association said in a statement.

In addition, as many as 200 headstones were damaged or knocked over at a Jewish cemetery in suburban St Louis late on Sunday or early on Monday.

The FBI said it was joining with the Justice Department’s Civil Rights Division to investigate “possible civil rights violations in connection with threats.”

US President Donald Trump condemned the attacks in public following a White House statement denouncing “hatred and hate-motivated violence” but failed to mention Jews or the string of threats and attacks on the Jewish community.

Speaking at the newly opened National Museum of African American History and Culture in Washington, notoriously racist Mr Trump said: “This tour was a meaningful reminder of why we have to fight bigotry, intolerance and hatred in all of its very ugly forms.”

The billionaire bigot went on: “The anti-semitic threats targeting our Jewish community and community centers are horrible and are painful and a very sad reminder of the work that still must be done to root out hate and prejudice and evil.”

Hillary Clinton earlier tweeted the attacks were “so troubling” that “everyone must speak out,” starting with the president.

Mr Trump drew criticism last month when he failed to mention Jews in his Holocaust Memorial Day statement.

Southern Poverty Law Centre spokesman Ryan Lenz said there had been an increase in racist incidents since Mr Trump’s election.

“People are much more willing to express their bigoted selves than they were prior to the election,” he said.
