Russia’s Supreme Court upheld Thursday a guilty verdict against Alexander Koptsev, sentenced in September to 16 years in prison for stabbing nine people in a Moscow Shul in January 2006, and for fueling religious hatred.

“The sentence comes into force as of today,” the verdict reads.

Koptsev, who was 20 at the time of the attack, charged into a Shul on January 11 shouting anti-Semitic slurs, and stabbed nine Yidden with a kitchen knife before being wrestled to the ground. In his final statement before the court, he apologized to the victims and their families.
