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.

Israeli forensics examiners have identified the remains of a deceased Israeli hostage handed over on Monday as those of Sergeant Major Tal Haimi, the prime minister’s office said.

Hamas clashes test Trump's Gaza peace deal, his top negotiators return to the region to shore up the ceasefire.

The vice president said that while he can't have "100% certainty that it's going to work," he has "great optimism the ceasefire is going to hold."

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.

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

Near-daily Israeli attacks have become the new normal in Lebanon, nearly a year after a U.S.-brokered truce halted the lastest conflict between Israel and Hezbollah.
