More than 10% of principals and senior education staff employed by the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) in the Gaza Strip are members of Hamas or Palestinian Islamic Jihad, according to a report published on Thursday.

The study, by Israeli non-profit organization IMPACT-se, noted that many continued to draw a regular salary after Hamas’s Oct. 7, 2023 massacre. Its publication comes less than two weeks after Israel’s Knesset barred UNRWA from operating in Israel over its terror ties.

For the study, IMPACT-se explored educational practices in five schools whose principals are senior UNRWA education officials, and under two of which (Al-Maghazi Boys Preparatory School B and Al-Zaytun Boys Preparatory School A) Hamas tunnels were found:

• Al Zaytun Boys Preparatory and Elementary School, whose principal, Mohammad Juma Shuwaideh, is a squad commander in Hamas’s Gaza Brigade.
