(JNS) The Hamas terror organization only has “a few days” to agree to a U.S.-proposed ceasefire extension, an Israeli government spokesman confirmed on Tuesday, March 4.

“If they don’t, the Cabinet will convene and decide on the next steps,” Omer Dostri, Israeli Prime Minister Benjamin Netanyahu’s spokesman, told Israel’s Army Radio.

The Security Cabinet, which is responsible for defense-related decisions and composed of senior ministers, is scheduled to meet on Sunday at 4 p.m., the Ynet outlet reported on Tuesday.

Jerusalem is developing a plan to resume the war in the Strip in four to six weeks in a decisive campaign to wipe out Hamas, The Washington Free Beacon reported on Friday, citing several current and former Israeli officials.

Netanyahu and IDF Israel Katz instructed Zamir to develop the plan, which is projected for completion when he enters office on Thursday, according to the report.

The plan is to conquer the entire Gaza Strip in one fell swoop with more than 50,000 soldiers, relocating the civilian population to humanitarian zones and waging a “ruthless ground campaign” in terrorist-heavy areas that will receive no humanitarian aid, according to the Beacon.

The campaign is to commence with a heavy aerial assault, followed by a reduction of aid entering the Strip. IDF divisions would simultaneously enter the Strip in the north, center and south, carving it into three parts.

The campaign could be paused if the Hamas leadership agrees to free captives, or if it disarms and goes into exile, the report added.

Israeli assessments indicate that Palestinian terrorist groups in the Strip are still holding 59 hostages. Of these, 24 are believed to be alive—all men—while 35, including three women, are believed to be deceased.

Phase 1 of the ceasefire, which went into effect on Jan. 19, formally expired at midnight on Saturday.
