The U.S. Senate is set to vote on legislation that would block arms sales to Israel, with lawmakers arguing that Israel is obstructing aid shipments to Gaza. The resolutions are not expected to pass due to strong bipartisan support for Israel, but supporters hope they will encourage Israel and the Biden administration to take more action. Gaza is facing a humanitarian crisis, with most of its population displaced and at risk of famine. The Biden administration previously warned Israel to improve aid flow to Gaza or face consequences, but many aid groups disagree with the assessment.
