At least 13 Jewish Community Centers were evacuated Tuesday, after the third wave of bomb threats this month was made against the religious centers.

This latest spate of threats, which came in between 10 a.m. and noon, targeted JCCs in at least 11 states and is being investigated by the FBI.

“The FBI and the Justice Department’s Civil Rights Division are investigating possible civil rights violations in connection with threats to Jewish Community Centers across the country,” the FBI said in a statement emailed to NBC News. “The FBI will collect all available facts and evidence, and will ensure this matter is investigated in a fair, thorough, and impartial manner. As this matter is ongoing, we are not able to comment further at this time.”
