STORY: Israel has yet to provide evidence for its accusations that hundreds of staff with the U.N. agency for Palestinian refugees – or UNRWA – are members of terrorist groups, according to a review of the agency's neutrality released on Monday.

The review also noted that UNRWA has a "more developed approach" to neutrality than other similar U.N. or aid groups, according to Catherine Colonna, a former French foreign minister appointed by the U.N. to lead the review.
