Israel has reopened two crossings in Gaza, while the key Rafah crossing will stay closed to the movement of people until further notice.

An Israeli security official said the transfer of aid into the territory is halted "until further notice," the first major test of the ceasefire.

Special envoy to the Middle East Steve Witkoff and President Donald Trump's son-in-law and businessman Jared Kushner arrived in Israel on Monday morning to bolster the ceasefire agreement and to continue implementation of the second phase of Trump's 20-point Gaza plan.

President Donald Trump warns Hamas the U.S.-brokered Gaza truce must hold, vowing serious consequences if violence resumes, as Vice President JD Vance to visit Israel.

Israeli fire killed three people near a ceasefire line in Gaza on Monday, medics said, with U.S. envoys expected in Israel to try to push forward the fragile truce that faced its gravest test so far over the weekend.

Israel launched a wave of attacks on Gaza after accusing Palestinian militants of attacking its forces across cease-fire lines. Both sides say they are still committed to the truce.

None of this means the ceasefire is about to collapse. Even though there will no doubt be further violations, for now a mix of self-interest and American pressure should ensure that Israel and Hamas remain party to the deal.
