London Mayor Sadiq Khan was among those who attended Synagogue on Saturday as part of the “Show up for Shabbat” initiative after the Pittsburgh shooting.
A week after 11 people were murdered at their shul, Rabbi Neil Janes implored people at West London synagogue to "focus on amplifying small and yet simple acts so that the voices of hope are louder than those of hate".
The mayor called the service “deeply moving", adding: "London stands shoulder-to-shoulder with the Jewish community here and around the world.”
