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.

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

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.

Israeli forces have pulled back to a boundary which leaves Israel in control of most of Gaza - keeping far-right ministers on Netanyahu's side, for now.

The body of a twelfth hostage returned to Israel from Gaza has been identified Sunday as Thai national Sonthaya Oakkharasri, as the ceasefire that brought a pause to two years of destruction in the Palestinian enclave comes under strain.
