A New Jersey high school student — reportedly a Jewish-Israeli — is facing possible bullying charges stemming from Twitter posts that school administrators called anti-Israel.

An assistant principal at Fair Lawn High told Bethany Koval, 16, on Wednesday that she could be formally charged under New Jersey's Anti-Bullying Bill of Rights Act, which could lead to suspension or expulsion from school, the Gothamist reported. The matter has been referred to the superintendent of schools.

In tweets about the 2014 Gaza war and the Israeli-Palestinian situation, Koval called Israel a "terrorist force" and said "Hamas is not extreme." Another post on the social media site expressed happiness that a pro-Israel classmate had unfollowed her. Koval did not identify the student, but told a friend she would provide the name in a private message.
