Family members of the remaining Israeli hostages still in Gaza are concerned about the next phase of the deal with Hamas after President Trump's comments about reshaping the Middle East. CBS News' Robert Berger explains.

It is believed that at least two of the six American hostages still held in Gaza are alive — Sagui Dekel-Chen, 35, who grew up in Bloomfield, Connecticut, and Edan Alexander, 19, from Tenafly, New Jersey. Four other Americans are believed to have been killed in captivity.

Israeli troops have pulled back to the edges of Gaza, the first hostages have been released and many Palestinians have returned to what remains of their homes in the first few days of the Israel-Hamas

The fragility of the truce between Israel and Hamas was laid bare on Saturday, after Israel accused Hamas of withholding a hostage, prompting a halt in the movement of Gazan civilians back to their homes in the north.

The chaotic release of several hostages in Khan Younis Thursday was described by Israeli leader Benjamin Netanyahu as “shocking.”

Hamas militants freed three male hostages held for more than a year in the Gaza Strip on Saturday and Israel released 183 Palestinian prisoners from Israeli jails in the fourth such exchange of a ceasefire deal that has halted 15 months of intense fighting.
