One of the three Americans killed in an attack at a synagogue in Israel had strong ties to the Boston area.

Rabbi Mosheh Twersky was one of four victims of the attack Tuesday in which two Palestinian cousins armed with meat cleavers and a gun stormed a Jerusalem synagogue during morning prayers. Police killed the attackers in a shootout.

Rabbi Twersky was the son of Rabbi Isadore Twersky, a founding director of Harvard University's Center for Jewish Studies. He died in 1997.

Mosheh Twersky was a 1973 graduate of the Maimonides School in Brookline, which was founded by his grandfather, Rabbi Joseph Soloveitchik.

The school said in a statement that it is "engulfed in grief and outrage."

Rabbi Twersky had lived in Jerusalem for about 30 years.
