Hamas handed over all 20 surviving hostages to Israel on Monday, a major step towards ending two years of devastating war in Gaza as U.S. President Donald Trump, who helped broker the truce, proclaimed it was "a great day," Reuters reported.

The Israeli military said it had received the remaining 13 hostages after a first batch of seven arrived earlier on Monday, announcements that prompted cheering, hugging and weeping among thousands waiting at Hostage Square in Tel Aviv.

"This is a great day. This is a new beginning," Trump said after arriving to a hero's welcome in Israel where he was addressing the Knesset before flying on to Egypt for a summit aimed at building conditions for a lasting peace in Gaza.
