(JTA) — An unauthorized drone was spotted flying over the Jewish school in Toulouse that was attacked in 2012.

Soldiers guarding the Ozar Hatorah school as part of a French government directive in the aftermath of the Jan. 9 attack on a kosher supermarket in Paris observed the drone on Sunday evening, French media reported.

The drone looped around the Roseraie neighborhood where the school is located and flew over Ozar Hatorah’s middle school and high school buildings, the guards said.

The incident occurred just one day after an unidentified man was spotted placing a bag containing Stars of David mixed with rags in front of a synagogue in a Toulouse suburb. Police are searching for the man and the people responsible for the drone.

March 19 will mark the third anniversary of the Ozar Hatorah attack, in which three children and a rabbi were shot dead. A commemoration ceremony is planned.
