A fight broke out between high school students visiting the Yad Vashem Holocaust Memorial and Museum in Jerusalem Thursday. The incident occurred after one student made a disparaging remark about a student from a different high school.

One of the two, who was aged 15, came from a school in Maaleh Adumim. The other, 17, attends a school in Hod Hasharon. The former made the remark to the latter, Channel 2 reported.

The 15-year-old was later ambushed by some 15 students, the report said. “They kicked me in my ribs, in my face.”

Yad Vashem said that the event was an out-of-the-ordinary occurrence.

A guard at the museum who tried to break up the fight was lightly injured.
