TEL AVIV, Israel (AP) — Israel approved plans Monday to capture the entire Gaza Strip and remain in the Palestinian territory for an unspecified amount of time, two Israeli officials said, a move that, if implemented, would vastly expand Israel’s operations in Gaza and likely bring fierce international opposition.

Israeli Cabinet ministers approved the plan in an early morning vote, hours after the Israeli military chief said the army was calling up tens of thousands of reserve soldiers.

The new plan, which the officials said was meant to help Israel achieve its war aims of defeating Hamas and freeing hostages held in Gaza, also calls for hundreds of thousands of Palestinians to move to Gaza’s south — which would likely lead to their forcible displacement and exacerbate an already dire humanitarian crisis.

One of the officials said the plan would be implemented gradually in an attempt to give efforts for a ceasefire and hostage release deal a chance to move ahead. Both officials spoke on condition of anonymity because they were discussing military plans.

The Israeli officials said the plan included the “capturing of the strip and the holding of territories.” The plan would also seek to prevent Hamas from distributing humanitarian aid, a role that Israel says strengthens the group’s rule in Gaza. It also accuses Hamas of keeping the aid for itself, without providing evidence. Aid workers deny there is a significant diversion of aid to militants, saying the U.N. strictly monitors distribution.

The officials said Israel was in touch with several countries about Trump’s plan to take over Gaza and relocate its population, under what Israel has termed “voluntary emigration.” That proposal has drawn widespread condemnation, including from Israel’s allies in Europe, and rights groups have warned it could be a war crime under international law.

For weeks, Israel has been trying to ratchet up pressure on Hamas to get the group to agree to its terms in the ceasefire negotiations. But the measures do not appear to have moved Hamas away from its negotiating positions.

The previous ceasefire was meant to lead the sides to negotiate an end to the war, but that has remained elusive. Israel says it won’t agree to end the war until Hamas’ governing and military capabilities are dismantled. Hamas, meanwhile, has sought an agreement that winds down the war without agreeing to disarm.

Israel’s expansion announcement angered families of hostages who fear that any extension of the conflict endangers their loved ones. The Hostages and Missing Families Forum, which supports families, urged Israel’s decision-makers to prioritize the hostages and secure a deal quickly.
