The U.S. Senate is due to vote on Wednesday on legislation that would block arms sales to Israel, backed by lawmakers who say Israel is obstructing aid shipments desperately needed by Palestinian civilians in Gaza. The "resolutions of disapproval" were filed by Senator Bernie Sanders, an independent from Vermont who caucuses with Democrats. Strong bipartisan support for Israel means the resolutions are not expected to pass, but backers hope they will encourage Israel's government and President Joe Biden's administration to do more to protect civilians in Gaza.
