Israel's military gave CBS News a rare look deep inside Gaza, where many questions still hang over the ruins of war and the future of 2 million Palestinians.

The soldiers manning the outpost are overseeing a delicate aspect of the now three-week-old ceasefire: the “yellow line,” a boundary of yellow blocks and flags laid out by the Israel Defense Forces that now mark the border between them and Hamas-controlled Gaza.

Israel on Tuesday said it had received the remains of Itay Chen, the last US-Israeli hostage held in Gaza, as part of the US-brokered ceasefire deal that came into effect last month.

The few buildings still standing in this expanse of northern Gaza protrude from the earth like broken bones. Around them, what was once a dense, urban neighborhood has been blown up, knocked down or otherwise crushed into debris and dust.

Israeli Defense Minister Israel Katz said on Sunday the Lebanese government must fulfill its commitment to disarm Hezbollah and remove it from southern Lebanon, as Israel continued to intermittently attack the group in the south of the country.

Hundreds of thousands took to the streets of Jerusalem on Thursday to protest against efforts to end an exemption from military service for Israel’s Haredi religious students.

The Israeli military attacked the Gaza Strip for a fourth day on Friday, killing three people, Palestinian health authorities said, in another test of a fragile ceasefire agreement.

The Red Cross said it transferred the unidentified remains of three people to Israel late Friday but they were still being examined and may not be those of missing hostages, an Israeli military official said.
