The Biden administration believes it has won assurances from Israel that it will not hit Iranian nuclear or oil sites as it looks to strike back following Iran's missile barrage earlier this month, two U.S. officials said Tuesday.

The administration also believes that sending a U.S. Terminal High Altitude Area Defense battery to Israel and roughly 100 soldiers to operate it has eased some of Israel's concerns about possible Iranian retaliation and general security issues.

The Biden administration has warned Israel that it must increase the amount of humanitarian aid it is allowing into Gaza within the next 30 days or it could risk losing access to U.S. weapons funding.

Secretary of State Antony Blinken and Defense Secretary Lloyd Austin warned their Israeli counterparts in a letter dated Sunday that the changes must occur.
