WASHINGTON—National security adviser Jake Sullivan told Israeli leaders that it was critical for them to begin transitioning their campaign in Gaza to more precise, targeted operations, in part of the U.S.’s full-court press in the region for the Israelis to begin to wrap up the conflict.

U.S. officials have said the U.S. wants to see the conflict end in weeks, not months, though the Biden administration continues to support Israel’s campaign to destroy Hamas’s ability to wage military operations or govern Gaza.
