Israel’s military said it had launched attacks across Gaza after Palestinian militants shot at its troops. The six-week-old cease-fire has been pierced periodically by bursts of violence.

Hamas has swiftly reestablished its hold over areas from which Israel withdrew, killing dozens of Palestinians it accused of collaborating with Israel.

Israel and Hamas took steps toward ending the two-year war that has devastated the Gaza Strip, but hard work lies ahead.

Health officials in Gaza have said identifying the remains handed over by Israel is complicated by a lack of DNA testing kits. Israel has not disclosed how many bodies it is holding or where they were recovered, but has been returning 15 for each set of hostage remains handed over.

Deep underneath the wreckage of Rafah, southern Gaza, the war is not over. Scores of Hamas militants, split up into independent cells, are trapped in tunnels underground behind Israeli lines, as mediators try to find a solution that doesn’t collapse the month-old ceasefire in Gaza.

As the first stage of the agreement nears its end, President Donald Trump’s son-in-law, Jared Kushner, met on Monday with Israeli Prime Minister Benjamin Netanyahu and his close confidant Ron Dermer in Jerusalem.

A Gaza company that operates water desalination plants serving nearly half of the enclave's population said on Tuesday it had resumed operations after Hamas-led security freed a staff member whom they detained on Monday.

Israel has received the remains of a hostage in Gaza that Hamas says is the body of an Israeli soldier who was killed in 2014 and has been held in Gaza for the past 11 years.
