It comes as Israel reportedly says the Rafah border crossing will stay closed over Hamas's delay in returning the bodies of hostages.

Israeli soldiers killed several Palestinians in northern Gaza on Tuesday, a day after US President Donald Trump touted the end of the two-year war in the coastal enclave on a whistle-stop visit to the Middle East.

Israel freed almost 2,000 Palestinians from its jails on Monday as part of a Gaza ceasefire deal, prompting emotional scenes of families reunited with loved ones, some of whom had spent decades behind bars.

Israel says it expects all of the 20 living hostages held in the Gaza Strip to be released Monday in its breakthrough ceasefire deal with Hamas.

In exchange for the return of the hostages, Israel will free 250 Palestinian prisoners, including those serving life sentences. That's in addition to releasing more than 1,700 detainees held without charge over the course of the war - including nearly two dozen children.

Israel's military said it opened fire on "several suspects" who were spotted crossing a boundary that troops pulled back to under the ceasefire deal.

Some Palestinians in the Gaza Strip, where Israel has for two years waged a brutal and systematic war against Hamas, are returning home and beginning to reckon with the destruction caused by the conflict.
