Israeli officials announced new allegations regarding the United Nations agency for Palestinian refugees employees’ ties to Gaza-based terrorist groups on Monday.

Israeli military spokesman Daniel Hagari said on Monday that roughly 450 employees had ties with Hamas and other Gazan terrorist groups, which is a significant development from the January allegations against UNRWA that a dozen employees participated in the Oct. 7 terrorist attacks. Those 12 were fired at the time and the U.N. has multiple investigations ongoing.
