The Biden administration has told Israel that it must work to avoid “significant further displacement” of Palestinian civilians in southern Gaza if it renews its ground campaign aimed at eradicating the Hamas militant group, senior US officials said.

The administration, seeking to avoid more large-scale civilian casualties or mass displacement like that seen before the current temporary pause in the fighting, underscored to the Israelis that they must operate with far greater precision in southern Gaza than they did in the north, the officials said, briefing reporters on condition of anonymity under ground rules set by the White House.

Amid mounting international and domestic pressure about the rising Palestinian death toll, the White House has begun to put greater pressure on Israel that the manner of the coming campaign must be “carefully thought through”, according to one of the officials. The Israelis have been receptive when administration officials have raised these concerns, the official said.

Prime Minister Benjamin Netanyahu has made clear that Israeli Defence Forces will eventually restart military operations after the conclusion of the current, temporary ceasefire that has allowed for an exchange of hostages taken by Hamas for Palestinian prisoners held by Israel.

President Joe Biden has said he would like to see the pause — which has also allowed a surge of much-needed humanitarian aid to get into Gaza — continue as long as feasible. Secretary of state Antony Blinken will return this week to West Asia as the US hopes to find a way to extend the ceasefire and get more hostages released, the state department said on Monday. It will be his third trip to the region since Israel’s war with Hamas began last month.

Still, Biden and top officials have also been clear-eyed about Israel’s desire to continue operations focused on Hamas that over the last seven weeks have largely focused on the north.

They have said they support Israel’s goal of eliminating Hamas’ control over Gaza and the threat it poses to Israeli civilians, but have grown more vocal about the need to protect the lives of Palestinian civilians.
