(JTA) — The Jewish school in France where a gunman killed three children and a teacher has received a rash of anti-Semitic hate mail and phone calls since the attack.

The Ozar Hatorah school in Toulouse complained to the local prosecutor about the harassing mail and phone calls, the French news agency AFP reported.

Prosecutor Michel Valet said Wednesday that he had ordered a police investigation into the incidents.

The school’s e-mail system reportedly filled up with messages calling for the murder of Jews and linking the attack to the Israeli-Palestinian conflict, according to AFP.

The gunman, Mohammed Merah, who was killed by police after a 30-hour siege, told French police that he killed the Jewish students at the school in revenge for Palestinian children killed in Gaza, and had killed three French soldiers the previous week for serving in Afghanistan.

Rabbi Jonathan Sandler, 30, and his two young sons, as well as the 8-year-old daughter of the school’s principal, were killed in the March 21 attack.

It was also reported Wednesday that Merah would be buried in Algeria at the request of his father.
