The United States and Israel have allowed tax-deductible donations to far-right groups that have blocked humanitarian aid from being delivered to the Gaza Strip. 

Three groups that have prevented humanitarian aid from reaching Gaza — including one accused of looting or destroying supplies — have raised more than $200,000 from donors in the U.S. and Israel, The Associated Press and the Israeli investigative site Shomrim have found in an examination of crowdfunding websites and other public records.

Incentivizing these donations by making them tax-deductible runs counter to America's and Israel’s stated commitments to allow unlimited food, water and medicine into Gaza, say groups working to get more aid into the territory. Donations have continued even after the U.S. imposed sanctions against one of these groups.

The three groups examined by AP and Shomrim have slowed the delivery of aid by blocking trucks on their way to Gaza, either by snarling traffic or simply standing in front of the main Kerem Shalom crossing into Gaza.
