The State Department in a much anticipated report on Friday evening said it's "reasonable to assess" that Israel used U.S.-made arms.
"It's reasonable to assess that in a number of instances, Israel has not acted in a manner that is consistent with international humanitarian law," Blinken said Sunday on CBS.in ways that did not sufficiently mitigate civilian harm, but it could not definitively conclude that any specific incident met the violation threshold.
The comments were Blinken's first public remarks on the report, which looked at use of U.S. weapons in conflict zones such as Israel and Ukraine.
But it is the assessment on Israel that has infuriated lawmakers on both sides of the aisle, with Republicans and Democrats arguing that President Joe Biden is trying to have it both ways on U.S. support for Israel in its war against Hamas. Biden paused a shipment of weapons to Israel last week that he said could be used by Israel to attack the densely populated city of Rafah in a manner that would cause significant civilian casualties.
