Anti-Semitic graffiti implying that Jews carried out the Sept. 11, 2001 attacks in the U.S. has been daubed on a synagogue and businesses in London.
The Star of David and the numbers "9/11" were spray-painted on several properties including South Hampstead Synagogue.
London's Metropolitan Police said they were investigating the racially motivated hate crime after being informed Saturday evening. They said no arrests had been made.
Metropolitan Police Inspector Kev Hailes said that the graffiti had been removed and that extra officers were being deployed to "provide some reassurance to local communities."
"This is clearly a concerning incident and one we are taking seriously," said Hailes. "We have liaised with our partners in order to remove the graffiti and various inquiries are underway to find who is responsible."
The inspector added that "Officers will be on patrol throughout the area in order to provide some reassurance to local communities. Please approach us if you have any questions or concerns."
The police asked for anyone who may have seen anything suspicious to call in and help the investigation.
Hailes added that “The Met remains committed to tackling hate crimes in all its forms, and we will continue to work with our partners and the public to do so."
London Mayor Sadiq Khan condemned the incident in a post on Twitter, saying there is no place for anti-Semitism in London.
Labour MP for Hampstead and Kilburn Tulip Siddiq called the graffiti "unbelievable, senseless, disgusting antisemitism at the heart of our community."
Jewish historian Simon Schama condemned the graffiti, saying: “Taken together with the stabbings in New York something truly monstrous is rising from the slime.”
The Board of Deputies of British Jews wrote on Twitter: "This is a reminder that antisemitism is still with us. We hope action is taken to find & punish the perpetrators. Let's all work to defeat antisemitism in 2020!"
