White House national security adviser Jake Sullivan has discussed moves to shift Israel’s attacks on Gaza to lower-intensity operations focused on high-value targets during his visit to Israel, Reuters reports.

But it would be “irresponsible” to give specific time frames for such a change, a senior administration official told reporters.

“There was a discussion in these meetings and also in our prior meetings, and in calls between the president and the prime minister, on kind of a shift in emphasis from high-tempo clearance operations, high-intensity clearance operations, which are ongoing now, to ultimately lower intensity focus on high-value targets, intelligence-driven raids, and those sorts of more narrow, surgical military objectives,” said the official, who asked not to be identified.
