United Torah Judaism MKs Uri Maklev and Moshe Gafni recieved envelopes containing white powder and threatening letters telling them to "go back to Brooklyn" on Sunday.
"We, the enlightened residents of the State of Israel, demand from you, the people of darkness, to stop living at our expense," the letter reads. "Take your striemels, your stinky beards and wigs, and go back to Brooklyn!"
